sounds very nice for my ears, especially with the ef 83.
noise is still an issue, have to layout a better psu i guess. its unregulated, just rectifier, caps and a choke and 290 instead of 250 volts.
the ef 86 is quite microfonic, maybe its worn out, i will replace it with another one. lots of gain with the ef 86, maybe nice for ribbons (i dont own any)
very nice distortion at highest input levels with the ef 83, will test it for git/drums recording.
i guess its a really simple project, the sound seems to be quite unique and coloured; some might call it vintage; i dont have any serious preamps lying around for a-b, so i compare it to what i´ve been working with in studios so far.
very cheap project indeed:
10 ? tube tape recorder from the flea market - tubes and psu
broken di-box for the output transformer
12 ? input transformer
15 ? resistors, caps, wires
today i was in viennas flee market again, bought another tape recorder, labelled "stuzzi stereo recorder 202" for 5?.
so i´m going for a stereo version next...
oh, one thing to mention: two month ago i didnt know nothing about valve/audio stuff.
i learned everything fom this wonderful place, and i´m just about getting into it.
thank you so much for sharing!
keep it going!
