OTL Headphone Amp project.

Well done. It looks great, and wonderful that it also sounds so good and that you are really happy with it. One day I will have to give an amp go!

I definitely recommend it; I got a huge amount of enjoyment out of the whole build-process from start to finish, a lot more than I would have gotten if I had elected to do a solid-state build instead.

I think I have posted a link to the original build-article I found on the HeadWize website in one of my earlier posts, in case anyone else wanted to have a go at building one for themselves, I reckon it's a great first Tube amp project, but I would still recommend familiarizing yourself with all the safety procedures for working on, and building high voltage electronic circuitry first, for safety's sake.


A bit later on this week, I'm going to measure all the voltages in my build with my multimeter, and post a full list of them in this thread, so that other builders can use them as diagnostics for their build in case they encounter any tech problems/issues, I will also post scans of updated versions of the schematics for my build with voltages at key points in the amplifier and power supply circuits as well, oh, that reminds me, I'll need to do a series of screenshots of the signal waveforms I see on the LCD of my Digital scope too.
