• WARNING: Tube/Valve amplifiers use potentially LETHAL HIGH VOLTAGES.
    Building, troubleshooting and testing of these amplifiers should only be
    performed by someone who is thoroughly familiar with
    the safety precautions around high voltages.

My 1st tube amp - still under construction but main electronic parts of the project already finished ~1month ago.
Already working:
1. amplifier (4x EL34, 2x ECC82, 2x 6N6P),fixed bias, voltage stabilisators for 285V, 420V, -60V and 6,3V (with slow voltage increase function). Delay for HV.
2. tone control +/- 6dB, 2 points with relay to switch off (goal for next winter to prepare tube preamplifier with tone cntrol and HI END DAC)
3. remote control for ALPS potentiometer and on/off for hole amp.
Under construction
1. VU meter based on 2xEM84 (PCBs already done)
2. chassis (AL + INOX + GLASS = modern look)

Sound? Incredible... It's pupming to Jamo S606 speakers to 25sqm room.

GM100 Stereo

I thought of using an OFF led in my new project
A GM100 SE STEREO amp.
You can definitely see when it's on.
At 17V 20A

Will take some time, doing the scematics.
I'll go for 40W SE or so

The RS607 looks like a little baby...

Hello

Can someone help me with a good 6L6GC tube amp schematic, please.;)
Something not over complicated.
Probably not the best place to ask but when I see all those nice tube gears hard to resist not to ask. Also want to follow these post.
PP or SE , I'm interested on both, I will buy all the parts after I found a good schematic.
Specially if runs high voltage power supp.

Greetings gabor:)

Can have a glance on the schematic please (driver ECC82/6N6P especially)?

Sure - project described on this site: Gegentakt-Verstärker in AB-Betrieb für EL34 / 6L6GC

Orginal schematic

Canceled VB408, I did stabilisator by use IRFP820 and Zener diodes (similar like for the EL34 Anodes).

As I said - chassis during preparation (aluminium milling, anodicoxidation, then assy, and top preparation - inox laser cutting etc). Should be ready in 2 months.
