26 Surfysonic 9 months ago Also, the Fender Musical Instruments under the Fender name makes it a post 1966 CBS amp, but it's had a lot of fiddling done so it's hard to say. The caps and wiring look like pre-CBS. All I can tell you for sure is that 022897 is an 8 ohm, Single Showman output transformer. I'm sure others here can read the date codes on the transformers...I never bothered to memorize them because I don't care when, just what. The cabinet seems to be from April '64. One would expect a '64 Showman to have a 125A30A output transformer, or a 125A29A if it was a Dual Showman. Thanks, Billy, as always! I truly appreciate your help. Guys on the Surf Guitar 101 forum who are really into this era of Fender amps who have access to the date codes and other info verified that it was a '67 Showman chassis in a '64 Showman cabinet and not a Dual Showman. It's all good as long as it sounds amazing. I don't plan on plugging this puppy in until it's been to a vintage amp tech next week to give it the once over. I'll likely get the tech to restore the missing tubes, rebias and whatever voodoo is needed. I want to pair it up with a tone ring 1x15 cabinet to play it as it was meant to be played. I am most likely going to put the Gomez El Sonido and 2x12 cab up for sale as I don't want to alter it as it was intended with the El Sonido. I'll probably go ahead and get a tone ring 1x15 cabinet made at Beaver Bottoms or RA Custom.
