1 Toxophilite 11 months ago Finally have the amp part of this stereo guitar amp 99% finished. 20 watts a side using 7189s in pushpull. Basically fender Ab763 (blackface) circuit except for an early 6G11 bias vary tremelo and a James(Baxandall) tone stack on the right channel. Left Channel has tremelo and reverb and a mix pot to send a pre reverb and tremelo signal to the right power amp. Right amp is straight up no effects. This was set up to be used with my roland Re-150 space echo. Dry signal into left channel (then into both power amps). Echo signal gets sent to the right channel and just teh right power amp. Sounds great i have a cabinet I made waiting. Going to use 2 12" lightweight speakers with a slightly outward angled baffle for better stereo spread. Amp is configured in a tweed sort of style(controls at back on top) in a homemade chassis using a Hammond organ AO-14 PT , hammond organ 20 watt OTs. A 10 henry choke that came from somewhere, reverb transformer and new components and tube sockets.Still have to add the tiny footswitch panel9for reverb and trem) and then mount in cabinet. Should be under 45lbs.
