Here is the finished pictures. I just need to build a speaker connection cord with 1/4 to 1/4 male plugs and also one with 1/4 to speaker connectors/clips so he can hook it up to any speaker situation. Platefire

Plate, nice work.  What do you think of the Master?  Does it work without messing with the natural interaction between the 2 volume pots?  Will it silence the amp completely?

Thanks Ed

There is no interaction because it's only a one channel amp. I used the other gain stage that the other channel would use for a hot switch.

I played it this weekend in my church band using my Aria 335 copy. I had to play around with the vol settings but I got what I wanted with the master at about 11:00 oclock, tone about 12:00 oclock and pre vol about 10:00 oclock as I recall. I'm happy with the MV and as I recall will completely silence the amp at "0" but on the other hand I haven't actually tested that, so I would have to double check to be sure.

The amp is really quiet regarding operational noise, so that's a plus. I really got chewed out today when my wife learned I was planning on giving this to my grandson without a cover over the tubes. She said he will smash the tubes! She may be right? Platefire
