Hi
Well Norm and Thomas I was succesful as far as the volume control goes. Now heres the bad news, when I got this radio I had no way of checking the tubes for condition, so I re tubed it completely with ones that were used but had been tested good with two that were new, the problem is I only pick up 2 stations and even those are not comming through very well, I have tried just about every antenna hook up and configuration you can think of, I live on a 3rd floor Apt. so at this point I'm at a total loss as to what too do next, I've just about given up all hope of getting this radio to work correctly, any ideas? HELP!!!!

I can't remember if I asked you this before, but have you aligned the circuits?

T.D.

Hi

Be sure the audio circuits are operating. Pin #2 on 27's & 45's must have positive voltage. Have you replaced the coupling cap between 27 tubes?

This radio is TRF so here is something you can try. Connect your antenna to the detector tuner. See if this brings in stations. If so work back one stage at a time.

Norm, no I have not replaced those capacitors, I will do that first and then see where I'm at, if it still is not working, then I will do exactly as you stated, thanks for the help from both of you, I hope I come up with something.

Mark did you check your resistors? I haven't looked at previous thread, but open bias resistors will cause weak reception. Actually, I think you should replace all them old resistors. And if you have, better check the joints.

:Hi All
Well Norm I replaced the one coupling capacitor like you said, also decided while I had it open to replace the rest of the bypass capacitors, after doing this, reception definitely improved! I think with a good antenna and possibly a better location than where I'm at it will work very well, I also removed the pot portion of the control, to date back to the earlier version of the 55C, it now picks up even better! I figure with the local distant switch which changes the regerative feedback loop I will still be ok even in stronger signal situations, that carbon portion was just not repairable, beleive me I tried, thanks again for all your help!!! Bill, yes I checked for the possible open bias resistors, did not find any that were open, and more suprizingly, they were still pretty much in tolerance! thanks for the info, I appreciate the input:)

:Hi Bill!
I owe you and apology! I thought those resisitors were in tolerance, but since I had done everything else to the radio, today I decided to open it up again, this time I disconnected each resisitor and checked them, man were you right!!!! most of them were way out of tolerance!!! one of them by 30K!!!! I replaced each and every one of them, WOW!!!! what a difference!!!! this radio works great!!!!!!!!! unbeleiveable!!!! thank you so much for the tip!!!! I owe you one!
Mark

Since you got your set going, perhaps you will want to leave it alone. Still, since it is a fairly simple design, tweaking it will not likely cause harm. If your radio was to have any tune-up adjustments (you say you cannot find any), they would be small trimmer condensers on each stage of the tuning condenser (whether this condenser is one bank of stages, or each stage is separate). You will not likely find a TRF with adjustable coils (slugs). Since I do not know what the physical design is of the tuning condensers (all one gang or separate units), I cannot tell you exactly where to go. Look on the tuning condenser gang/units for trimmers, though. If it is a gang and is enclosed in a housing, you will have to open up the housing. All you have to do, though, is tune in a soft station somewhere towards 1400 KC. Then adjust each trimmer for maximum output. If the station does not line up with its appropriate mark at first, edge the dial off of the station towards where it should fall, and then adjust the trimmers for maximum output for this new spot. Keep doing this until the station is right where it should be.

Sometimes trimmers that are mounted on the tuning condensers are not represented in the schematic, as they are not separate units but are part of the condenser. It is usually customary, though, even in TRF sets, to provide trimmers. Perfect matching components are rare, and there must be a means of matching them. When aligning the radio, should it not perform well at other parts of the dial, remember where the station was that you used to do the alignment before you performed the alignment. Adjust it back to where it was if everything doesn't work out and see if this is what caused the trouble. Sometimes a radio is adjusted with some station mis-alignment at the factory to aid sensitivity. Before performing an alignment, be sure that the dial stops moving at the stop marks (if stop marks are provided). If your set happens to have poor synchronization due to mis-matched parts(stations line up at one end or are sensitive at one end, but do not do one or the other or both at the other end), tweak each end of the dial until the entire dial is about how you would like it to be. Usually TRF radios are not selective enough to have these problems. This is more of a super heterodyne problem.

:Hi Thomas
I will look again, but when I had the radio chassis out all the times working on it, I don't remember seeing any trimmers on the tunning capacitors, there are 4 of them and they are all ganged togeather, one plus is that they are out in the open, so if there are any trimmers they should be plainly visable, as far as the stations lining up on the dial, so far they all seem to be tunning in loud and clear where they should on the dial, however I will double check again for sure, thanks for your info:)
Mark

Well, if they are all lining up to where they should be, and they're loud and clear, chances are, especially if the set has never been worked on before, that all of the circuits are aligned as they should be. If that is the case, well enough is good enough.

Mark: Aligning the AK-55 is simple enough, but AK always wanted you to drill holes in the capacity plate that mounts over the tubes. Otherwise you wouldn't have access to the trimmers. If you align it with the plate off, the alignment will be off when you replace it. As mentioned earlier, if it's performing nicely, leave it alone. If you ever need to align it, try getting a similar sized aluminum plate at the hardware store, and drill matching mounting holes and alignment holes. That way you don't have to butcher up a nice radio.
Good luck, Steve

: Hi Steve
The only things I see that could be trimmers look like regular slotted screws that go through a PC board like material, but all they look like they do is mount the variable tunning capacitors too the chassis frame, am I looking at this wrong? are these the actual trimmers?
Mark

A trimmer condenser is simply a couple or several metal plates insulated by mica. A screw, which is also usually insulated from the former with mica, is used to compress the plates together. Bringing them together increases capacity and bringing them apart decreases capacity. Look at the screws and such and see if this is what you have. In some cases, you will find a single plate insulated from the metal frame with a screw going to the metal frame. Bringing this plate closer to the metal frame increases the capacity between it and the frame. Since the frame of a tuning condenser is part of one side of the condenser, using the frame as part of the trimmer is a logical and simplifying method of making a trimmer. In other cases the affair is on its own phenolic wafer or ceramic piece.

Still, if you are having this much trouble locating the trimmers, and the radio pulls in a lot of stations, don't worry about it until the set starts to fail. Just enjoy the radio. These parts do not get out of alignment on their own anyway. Someone would have to tamper with either the coils or the trimmers before you obtained the set, and with a set like this, simply moving wires around a bit does not affect performance much at all. (More sensitive short wave sets are touchy when it comes to slightly moving a component or wire.)

My pleasure, Mark

Mark: the trimmer screws are located on the top of each of the 3 tuning condensers. If it's playing fine, leave them alone. Besides, you'll never get them adjusted right if you have the capacity plate (over the tubes) off.
