Am starting to restore a very old Gulbransen Radio. It looks to be from the 1930's era (art deco styling) but someone has used a post-office stamp & stamped 1 May 1950 in a few places on the chassis. Tried to browse the Gulbransen section of circuits on this site but was told I was downloading too much & I do NOT want to make the hall of shame on the front page.
Any advice would be warmly welcomed - it was made in the USA, not New Zealand & has a 240-volt mains transformer.

Hi John

Listing tubes may help. Radios made for use in US seldom have 240 volt input option.

Hello Norm, thanx for the reply. Lineup is: a very rusty 6K7, an extreamly clean converter - judging by its construction I would say it's a 6K8G. 6Q7 6V6 & a balloon-style rectifier. This has its own winding but as I haven't plugged the set in yet, not sure if it's a four or five volt heater. It is direcetly heated though.
Then, along the side there's a shabby EF39 & a 6C6. I guess the EF39 is a foreigner - would have been a 6K7G originally?

& yes, the mains transformer is not original. It's an upright one & looks as though it was made in the 1960's . The hole in the chassis is for a horizontal mount.

Whoops! 4got to mention the magic eye - it's a 6G5G. REAL old.

Hi John

Gulbransen radios were made by Wells Gardner. There are several close but none match you tube line up. You listed 8 tubes. As mentioned EF89 is European and would have been a replacement.

Wells Gardner A15 is somewhat similar. 6U7 = 6K7, 6K6 = 6F6, 6U5 = 6G5.

Any chance the 6C6 socket was added later? It's not normally used with the others listed. Other tubes are octal. 6C6 is old style, 6 pin. Eye tubes were always 6 pin.

Transformer may have been replaced for 240 volt operation?

Yo Norm, thank you so much for all your time & research. There are no pushbutton presets on the front as described in Riders - nor can I see any evidence of a phono socket. Just a pity I can't post a pic of the front of the Radio. Yes, I wondered about the 6C6 also. The socket looks "original" but if replaced a long time ago, this would be hard to prove. Best guess: may have been be a 76 configured as a Cathode-follower?
Again, thanks heaps for your help in this.
John Roberts.
