Tube Amp Archive

Okay I'll try playing with values.

It doesn't have a 4 ohm tap.

I've acquired a m102 organ with an ao29 and ao44 chassis. I also have a ao43 chassis that I'm planning on doing sluckey's plexi6v6 build with but need to wait for some funding. The ao44 chassis seems like a pretty good candidate for a fairly already complete build that I need few parts to complete. ...

I'll check them out. The only thing I was trying to do is either get everything from one place online or in town here. Saves shipping. Going to have to wait for a bit to get funding anyway. I appreciate all the info and help. Just going to stick to the Sluckley plan instead of trying to do anything ...

Damn, I was looking at the tube compliment the h100 organ comes with and got thinking this would almost work with 7591 tubes. But on second thought, I should just stick to the schematic that I have because it's been built and tested. I think they'd likely melt the output transformer. Wait until I ge...

Okay I can look into those. I did find the .68uf@100v locally from a different supplier. I was trying to keep them all mallory 150s but I did find this vishay for the .1uf cap. Would it be fine? If I order from 10 different suppliers I'm going to get killed on shipping and I'd prefer to keep everyth...

One more question.... the Mallory caps in the circuit, I can only find 630v even for the ones rated for 100v and 250v. Are these the same as electrolytic caps where as long as the voltage is rated higher, you're good? Thanks in advance.

That's good to know. I was planning on using the transformers and choke also. I was also going to use some of the 12ax7 tubes. They're all 1963 rca's so they might or might not be good. Thinking they probably had a pretty easy life in an organ.

Yes Sluckley, I've seen all that. Just being new at this and all of the reading I've done, and parts availability locally, I just wanted to verify those things. Did you use 6v6s tubes? They look like them but I can't tell from the pics.thanks

Thanks so much Colossal. I've got to collect some parts together. For the mica caps it says generic but they are 500v. The it's the only generic cap they sell. Everything else is like F&T or sprague so I'm assuming it must be decent quality. My neighbor is going to give me his h100 organ so I'll hav...

Hello everyone. I'm new to the forum, and new to playing with amps. I just picked up a chassis out of a hammond L100. The chassis is a AO43. I've read the transformers are suitable for various amp builds. I've always wanted to build a little marshall style amp like a 18w or a JTM45. I had originally...
