I kinda forgot about it but always hoped I would find another and run them as mono blocks.
Well, I finally found another with operating instructions and schematics.

I did a dim bulb test and a quick run up and it works, I will change the caps of both with the same type to make them even sounding, even put same manufacturer tubes, unfortunately the output tubes of the

Real easy and straightforward build underneath and looking forward to the results.,,

Wow, I'm impressed at your patience!

Sargent Rayment made some neat stuff, but they're not easy to find. Should be fun!
 
I have two Sargent-Rayment SR88 mono tube amps that I had restored. They sound very good. I usually run them through Magnaplanars with two 12 inch Mitsubishi honeycomb woofers being used as subwoofers on a separate amp. I'm using them with a cheap Chinese tube preamp which seems to do the job so far. The SR amps pull about 130 watts each and output 15 watts class A. They can really heat up the room, which I why I usually use them in winter. I hope you enjoy yours as much as I enjoy mine!

As a side note: Mitsibishi honeycomb woofer speakers have incredible transient response and low distortion. Unfortunately, the mids are often blown even though they had circuit breakers on many models. The midrange drivers are not available for love nor money and can't be reconed. If you know differently please tell me. I have some blown mids saved up. So it makes sense to disconnect all the speakers except the honeycomb woofers and leave them in the original cabinet. Then you have a nice passive subwoofer setup! Plus, you may be able to get the speakers cheap if the mids are blown. Works for me, anyway.
