Hi, it's been a while because I have moved since my last post. I am now set up in the current house and started doing the mods to this amp. I thought I heard on one of the videos that you can mod an A10 just by following instructions for the A12. Now I am not so sure. For example, on the front end tube socket, bare like at the beginning of video 2, my A10 does not have a wire going to pin 9 and pins 4 and 5 each have a wire but they are not connected to each other. Skunkie says it is easy to change an A10 to an A12 but I can not find instructions.
Appreciate any help...
