I want to make an amp using 807 tubes preferably using ultralinear tap opt.
Can someone share me the schematic that is working using this tube?
Your help will be very much appreciated.
Thanks.🙂

I haven't built it amp myself, but this offering by JC Morrison looks interesting (though there are a few ambiguities in the schematic). More info here.
How much power do you need? Triode-mode Class A PP 807 can achieve impressive distortion figures before feedback (0.6%), but power will be limited to around 6W.
807 UL anode characterstics from Audiomatica's website, just for interest.
EDIT: How could I forget.... The "Ultra-Linear" amplifier by Hafler and Keroes here. It uses 6L6s, but they're basically 807s without topcaps.

An externally hosted image should be here but it was not working when we last tested it.

Not Ultra-Linear... but....
Why not try something like Gary Pimm's PP1624 amp? I believe a 1624 is essentially a DH 807.
It isn't an UL amp, but the local feedback around the output stage ensures that it has a low output impedance and low distortion even though it operates in pentode mode.
It's good for around 10W.

s2kov, search for the RH807 amp in the forum. it was designed by Aleksandar Kitic. just connect the screen grid to the UL tap of your transformer.
you can also try the Gordon Rankin 807 amplifier from sound practices.
