Hi Gordon,

I found this schematic that Steve Lucky drew in Viso. He does really nice drawings.

This was to make things work with EL84 valves. I will want to give this a try, but I decided to build the 6973 version first. I hope it will sound close to the original vintage Supro amps.

After the build is finished, I may see what you think about modifications that may be needed to change the tone. No two amps sound exactly the same, and although Magnetic Components is still in buisness making PT and OT, I assume they are not exactly the same as 1965.





By the way, I had a conversation with Trev today, and he is in the middle of a real expedition in the western part of the country. I hope to see some photos soon. Some kangaroos playing guitar to BIAB tracks...lol


Cheers,

Billy
