6KN6-PP-guitar slave

davorin · 21st March 2009, 05:48 PM

Halo! Have anybody experience with 6KN& or 42KN6 tubes? I just finished PP guitar "slave" amplifier, with fantastic sound and plenty of power (~28V/8 ohms at start of clipping=~100W RMS; ~23V/8 oms=70W RMS with ~2%THD).

Here is schematic (hand draw).

Not bad at all! Great to see some sweeps make music

How is the cooling done? Straight convection?

Cheers!

Yes, but finally plan is mount amp in 19´rack/box with fans (also with pre-amp, noise-gate, hall-effect and main voltage conditioner).

Very good sir!

I would suggest though a computer PS fan in there maybe, just incase it's operated outside the rack (portability for gigs/remote recording) or main fan failure.

Cheers!

Yes, good idea, but I must find very slim model of fun (max 15mm).

Good usage of RCA sockets.

Thanks for sharing!
