Title: Identify MM Tranny
Post by: p2pAmps on October 13, 2016, 08:52:35 am: Ok Mercury experts, A guy came in my shop last night and gave me a chassis he had laying around. I of course stripped it down as it was not the kinda of work I do. The amp (who know what) was loaded with 2 - 6V6s and a 5U4 + 2 preamp tubes. Anyway, the trannies is what I was really interested in. They are MM and I am trying to sort out what I can build with them.

Do you MM guys recognize what this PT is and what I can build with it. Before you ask I have not measured them yet as it was late and my pillow was calling me.

There are a lot of amps that fit that footprint. And you can probably use EL84s rather than 6V6s. Take your pick.

Yeah, I have so many damn amps now I wondering what to build next LOL. I traded a 67 BM for a super cool Vibrolux Reverb last night, go figure. I didn't need it but could not pass it up either. It's a sickness I have...

Post by: p2pAmps on October 13, 2016, 09:29:36 am: Well what I really want to build next is a cool steel guitar amp. Like a single channel AB763, no Tremolo, KT66s, 5AR4, etc etc. Maybe a 1x12 combo...

Post by: sluckey on October 13, 2016, 09:32:40 am: That sounds like a lite version of what you've been building.

Post by: p2pAmps on October 13, 2016, 09:35:19 am: Yeah I guess it is. I just have this thing in my head about a cool tube steel amp. I have several steel amps now like a NV400 and a Walker Stereo Steel. Did a session last week and used my Princeton on steel and it was very nice. Milkman is making some nice tube steel stuff as well
