Re: Ultimate Hammond Conversions thread

[/quote]12 on the green??? What does that mean? How are you measuring that? What is the other meter probe connected to? The green has nothing to do with the yellow wires. The green is a center tap for the brown wires only. Did you do the continuity check I suggested? [/quote] Big mistake. :roll: It ...

Re: Ultimate Hammond Conversions thread

That's it! The jpg shows the same outputs as mine. I thought I had a pic to upload mine but I either deleted it or save it to some odd folder. The voltages I posted above are unloaded with the PT sitting on a bench. The yellow is 5.8VAC with 12 on the single green. Based on what I've found so far do...

Re:PT with single green wire?

I'm back on my 5E3 build with spare iron and other parts from the A0-29 and have a question about the PT. The part number is A-A0-22111 4. I've tested the wires and have 6.7vac on brown-brown heaters 670vav red-red 335vac red\yellow center tap But I have just one green wire instead of 2 as expected ...

Re: 6J5 in preamp?

Great info. frank.pocnet.net is currently my favorite site of the week. Received the amp today. It's clean and in great shape physically but doesn't look like it's ever been serviced. I haven't tested anything yet but the wax filter caps are all sticky and gummy so they will be replaced which brings...

Re: 6J5 in preamp?

Thanks everyone for the info. I'm feeling a little better about the socket now that I know there are options. I was thinking about a 6Sxx of some kind and that was going to be my next question but you're way ahead of me.

6J5 in preamp?

I posted in the Hammond thread about converting an AO-29 to a 5E3 but found a loaded chassis that is smaller in size and may be much closer to what I want, and it's dirt cheap. My question is with the 6J5 on the input. I may be a novice, but to me that's an odd tube for a guitar amp and if I need to...

Re: Ultimate Hammond Conversions thread

I appreciate the reply. This is the info I've been looking for. I've been busy and probably won't get to look at the PT again for a few days, but when I do I'd like to determine the voltage so I can move ahead with my plans. Is there anything on the PT that would tell me if the HT is 320 or 380? If ...

Re: Ultimate Hammond Conversions thread

Hi all. I searched first but did not find an answer and would appreciate a nod in the right direction. I have an AO-29 complete with tubes and would like to make a 5E3 or similar 15-20 watt amp. What I'm trying to determine is if my transformers from the 29 can be used. The PT is stamped 22111-4 but...
