Sir Pinobit . . . . .
Since that's being a circa '61'ish unit and with a tooobie lineup of:
ECC85---ECH81---EF89---EABC80---EL95
How's about trying this . . . . . and seeing how it fits ?

Sr Pinobit. . . .
If that is the case, I would suspect that the problem would either be the power supplys SSF E250 C50 rectifier
being bad or the probably very aged companion filter capacitor(s) on past it . . . two 50 ufds . . . either being very leaky or shorted.
Ohhhhhhhh Mamma mia . . .!
Con la radio bruciare il fusibile, mi viene da pensare: o una perdita o un cortocircuito SSF E250 C50 raddrizzatore in unità.
O il doppio a 50 anni ufd condensatore elettrolitico nell'unità che è molto le perdite o in corto.

Hi Edd, now with this schematic is better, yes, "SSF E250 C50" diode is not present is replaced with a "1N2007" (I think) maybe this is not appropriate.
In internet I can't find images of original diode.

I think my radio is some "componentless" without component the 315ma fuse is broken when switch on the radio ...every time. Sorry for my bad english.

Sir Pinobit . . . .
With you expressing a degree of skepticism on the part numbering of the newer generation diode replacement
for the radios original old selenium rectifier.
I am sure that the number is not a 2007 , but instead the one we commonly use in the form of a 1N4007.
Its a look'a lik'a :
 http://t0.gstatic.com/images?q=tbn:ANd9GcSG8tADu56fZAwoD1MDTCsNFuJVEMmusA2_a7wqVMNujWQyYu6x>
(It progressively is rotating each pic of 3 so that you can make out the numbering.)
Check out that 1N4007 diode to see if it is dead shorted, if not then lift one end of the diode out of circuit and then power up the set to see if it is still blowing the fuse ?
If so, for a start, you then exlore the possibility of one of the 50 ufd electrolytics or else a B+ to to ground
bypassing capacitor , elsewhere in the set . . . BUT . . . I don't see any critical ones, since they are ALL being isolated apart, through higher value resistors in series with them !
ORA. . . . in mia Italiano . . .(di un bambino di tre anni)
Con te che esprime un certo scetticismo da parte numerazione della sostituzione nuova generazione a diodi per
l'originale raddrizzatore radio vecchio selenio.
Sono certo che il numero non è un 2007, ma quello che usano comunemente in forma di un 1N4007.
(Si sta ruotando progressivamente ogni foto di 3 in modo che si può fare la numerazione.) Verificare che diodo 1N4007 per vedere se è morto in cortocircuito, se non sollevare una estremità del diodo di circuito e quindi accendere l'apparecchio per vedere se è ancora bruciare il fusibile?
Se è così, tanto per cominciare, è quindi exlore la possibilità di uno dei 50 elettrolitici flash USB o un altro
+ B a condensatore a terra bypassando, in altre parti del set. . . MA. . . Non vedo eventuali criticità, dal momento che sono TUTTI essere isolati a parte, attraverso resistenze di valore più alto in serie con loro!
Addio. . e buona fortuna!

Hi, sorry for minstake, yes, the diode is 1N4007, and unfortunately is good, the polarity is correct, the doble elettrolitic is good too, I have tryed to change this but whitout fortune, the fuse is still exloding. I continue whit my search.

Sr Pinobit . . . .
Just to cover one thing initially . . . that radio is capable of operating on BOTH 120VAC or your 220VAC.
Check to be sure the the hot side of the line . . .with the fuse is going to the GREEN wire of the power transformer and not the RED wire.
I guess that the next logical test would be to disconnect the MAIN line of the B+ that goes up to the the center tap of the AF output transformer and place a ~5000 ohm at 15-20 watt wirewound resistor as a load from the input 50 ufd filter to ground .
If you don't have such , you might investigate the use of a small 15-25 watt incandescant lamp @ 220 VAC from a sewing machine -microwave oven-refrigerator's internal light.
What you would do is temporarily connect /wire the lamp in series with an additional series 1k @ ~5 watt " sacrificial " resistor into circuit with clip leads and see if the unit THEN makes it PAST the NORMAL fuse popping time.
BUT , if being successful , you will need to pull the AC plug before the then developed B+ starts exceeding the 220 V threshold and then going on UPWARDS towards its expected 270 . . . .FLASH ! 
This then points the finger towards the AF output transformer, tube or something tied into that higher level of B+ circuitry.
BECAUSE the NEXT lower B+ voltage level has the current limiting of a 1 K resistor prohibiting a problem.
Italiano . . . . Giusto per coprire una cosa di più inizialmente. . . che la radio è in grado di operare su ENTRAMBI 120VAC o 220VAC tuoi.
Controllare per assicurarsi che il lato caldo della linea. . . con il fusibile sta al filo VERDE del trasformatore di potenza e non il filo ROSSO.
Credo che il test logico successivo sarebbe quello di scollegare la linea principale del + B che va fino al rubinetto centrale del trasformatore di uscita AF e mettere un 200-220 o 250 ohm ~ Resistenza a 15-20 watt a filo come un carico dall'ingresso 50 UFD filtro a terra.
Se non si dispone di tale, si potrebbe esaminare l'uso di un piccolo 15-25 watt incandescant lampada @ 220 VAC dalla luce interna di una macchina da cucire a microonde forno-frigorifero. Quello che vorrei fare è collegare temporaneamente / collegare la lampada in serie con una serie supplementare 1k @ ~ 5 watt resistenza "sacrificale" in circuiti con cavi di clip e vedere se l'unità effettuati, è passato il tempo fusibile NORMALE popping.
MA, se avere successo, è necessario staccare la spina CA prima del poi sviluppato B + inizia superamento della soglia di 220 V e poi andare in alto verso i previsti 270 volts.
FLASH !
Questo sottolinea poi il dito verso il trasformatore di uscita AF, tubo o qualcosa legato in quel livello più elevato di B + circuiti.
Perché il prossimo basso livello B + di tensione ha la limitazione della corrente di una resistenza di 1 K che vieta un problema. Alla fine per ora . . . . .

If at first, you DO succeed, try not to look too surprised.

Surprise! II have a little sound in the speaker!
Now I'm sure, the original diode (apparently broken) Siemens E250 C50 is not replaceable with the 1N4007 or another diode, I don't know why, maybe this radio is possessed. The original diode is a open circuit, but without this the radio don't work. Naturally now I'm happy, but the waay still long. Thanks for your last message, now I'm ready for the next step, restoration before of test and assebling.

In AM is ok, but is mute in UK (FM) mode.

The ECC85 is dead, trying whit another ECC85 is perfectly working, now I hope to find a new valve but is not easy.
And at the end I need to eliminate the main faul, a false contact in a fuse place (not the fuse continuoasly exploding, is another connedted from the main power to the ground). This is the cause of total fault in the radio.

Pinobit:
Fuse from main power to ground sounds wrong to me. A fuse there would blow if there were a fault or not. A trick often useful in cases like yours is to have a light bulb in series with the main power, approximately the Wattage of the radio. A short in the radio will make the bulb burn brightly, and when the short is found it will burn dimly. Such a device is very usefun in testing circuit problems such as you have.

Yes, german electronic is very strange but good. In this radio I have 4 fuses 2,5A for main (voltage selector) 2,5A is this to ground, another is located before the main fuse and after the transformer.
Yesterday, happly listening my radio at low volume because are the 05:10am, ...but only for 20 or 30 minutes, a flame exploding in the back side of the radio, the main fuse is broken, the radio (transformer) in short circuit. whats happened?
Is very delicate, I this currents in the global circuit are elevate, maybe some resistor is old.
11/1/2012 6:37:10 AMPinobit(103025:103021)
Fortune, the transformer is good, the first capacitor 22n located after the main fuse and and before the ground fuse is clearly broken and in short, now I try to find a new capacitor in my trash (the last and unique ecc85 I have find there) and change.
Speriamo bene!

Finally in test, after the last 10 broken fuses, now have not a fat fuse but a timed, maybe the wrong type it's causing the fault. Ok 40 minutes in test, I hope for 2 hours, but later I need to change some components more. The lamp is not the correct lamp as dimensions fisically,is too long, this is unsafe because is touching to the plastic and cartoon box and is a little hot. I need to attach the cable and to screw the metallic chassis.

Pinobit:
I would not be concerned about using a slow blowing fuse in a tube type radio, as the tubes can take little abuse in the time it takes for the fuse to blow. In the airplanes I used to maintain, every wire was protcted by a circuit breaker, but just about every box had a fast blowing fuse to protect the transistors, as the circuit breakers operated too slowly.

...mmm yes, that is true, bur for now tha radio is perfectly working, now I'm creating the back side cover, maybe later I try newly whit the fast fuse but is very sensible because some resistor have changed value.

It is great that you have the radio working. I would check some Voltages at the tube sockets, and if they are close to the schematic, then put it together and enjoy it.
