I am starting a patch job on a spare AW23 Speaker.  Before I start, I decided to wire check the FC, VC, and all the connections to the plugs.  It appears that the speaker wiring has not been modified…Continue

Hi everyone,  I recently purchased a "custom" AW27.  I say custom because it was constructed by modifying an AW23 tuner and putting together two AW23 amp chasses.  It sits on a custom made Napier…Continue

"I agree - leave those 3 apron mounted cap/coil units alone unless there is a good reason. Ditto for the previous 12 tube DELUXE. I have never had a reason for the several AW-12's and AW-15's over the years."

WTB Speaker for Scott Masterpiece

Posted on October 1, 2019 at 7:05pm 2 Comments

I picked up a tuner and amp at the recent radio auction in Indy, but no speaker.  So I am looking for one.  It has an octal plug on it and the speaker has two field coils:

One at 680 ohms and the other is 125+65 ohms (it is also split)

Can anyone point me in the right direction?

Thanks,

Joe

I am looking for a PS. Don't need tubes necessarily.  

Anyone have one for sale?

Philly Amp wiring

Posted on July 20, 2016 at 9:57pm 1 Comment

I am working on a Philly amp and am finding a number of wiring mods that deviate from the schematic. Some are due to someone bypassing a bad audio transformer and for adding a second phone plug input with volume/mixing pots.

But I also found a 125 ohm Candohm type resistor that is factory mounted to the side of the amp chassis. It is connected in series to the cap connected to pin 6 of the set plug socket and then tied to ground. It doesn't show on the schematics that I…
