OTL Headphone Amp project.

Update:


I think I have finally found the OTL Headphone amp circuit I want to build, this particular design uses a set of three 6N1P twin triodes and it looks like it can drive load impedances down to about 64 Ohms, some of the other designs I was considering building aren't happy with driving low impedance loads as low as that, here's a link to the webpage:

This one looks like a relatively easy one to build and I think Evatco stock both the 6N1P tube and the Hammond 269AX power transformer.

Turns out I was right, Evatco do stock the 6N1P tube:

Evatco don't seem to have the Hammond 269AX power transformer in stock, but, Mouser Electronics do seem to stock it, so I'll have to order it online from there.

I just found the perfect application/use for my diy scratch-build 6N1P OTL Headphone amp build, currently I'm using a pair of wireless headphones with my new Blaupunkt HDTV, while the wireless headphones works with it, it has a nasty habit of the rechargeable battery going flat at annoying times, I can't use a pair of wired headphones with the Blaupunkt because there's no headphone out socket, but, it does have stereo RCA Audio Line-Outs on the back, all I would need to do is connect up my 6N1P OTL Headphone amp to the stereo RCA line outs and plug in a pair of headphones.
