Tube Amp Archive

Cheers Martin, also ive noticed that there is a missing jack on the 3rd gen layout i believe its the power amp? out of curiosity, why has that been taken out? I've finally sourced and received about 98% of the parts (excluding transformers) and im starting to drill out the chassis and dry fitting th...

Thanks again for the responses guys. So for the FET i could just leave it all out except the 150k resistor between the NOR jack and B+5? I have sourced all the parts apart from the relay power transformer. i am having trouble finding the triad f-313x here in australia. I was wondering if i could use...

Hey guys, i have a few new questions regarding the build, please bare with me, im a complete newbie. Q1. Looking over the ods 3rd gen layout, i saw this and was wondering what it is. (image below) Q2. What is the underlying Isolation material underneath the circuit boards? Q3. How simple would it be...

so neither transformer will do? On the ods layout i see it has written 022871 for the ot. or do you mean it wont achieve that tight bass tonality?

Do you guys have any transformers that you can recommend?

I have a 16 ohm orange cab that i will use but im also considering putting it in a combo eventually (not sure which speakers yet). Probably going for more of the second option with the tight bass i guess. Sorry about that, martin manning, i thought it was more related to technical discussion than a ...

Im just about to start my first build based off of the stickied 3rd gen dumble thread in the dumble files sub forum and the ceriatone ots 50 w layout found on the website. ive ordered most of the parts, but am yet to purch...
