your opinion on these clones?
I assembled one several years ago and it never touched my heart

I find it really really good. An alive amplifier with low bias current consumption! It's always a matter of taste. By example I find UCD amplifier flat and borring, but often use them in my amplifiers because it's fun to deal with!

What is your favorite amplifier ? I always want to try new things.I find it really really good. An alive amplifier with low bias current consumption! It's always a matter of taste. By example I find UCD amplifier flat and borring, but often use them in my amplifiers because it's fun to deal with!

I'm almost all tubes now but I still love my JLH69s and my Naim clone.
I also have several mosquito zenquito buzquito zenotron and NRDS 30 w amps left.
you live in France ?

 

[SDF]

Yes I live in Toulouse in France. Tubes are often really pleasant to listen! I just owned hybrid amplifier but never real valves amplifier with output transformer!

JLH69 is so many times quote as really good amplifier, I would like try it one day but I don't like high bias current and big consumption one!

My Vendetta SCP-2B phono preamp, non-inverting phase version. It has been constantly on for one year. No hum and buzz, low dc offset and noise, neutral sound. Built with genuine Toshiba J-fets and Hitachi lateral MOS-fets.

NAD 3400.
It's my challenge to learn and repair.
Started with recap.
Then some pwr tr stopped working....

Have 4 off them though. Started recap one of the working ones.
15000uf filter caps in the low rail pwr. Instead of 10000uf.
It's a mess with wires everywhere in this amp, so i will try sort them out, and move them under the board instead.

Waiting for parts,

Good luck !

 

[oggioffshore]

Good luck !

Cheers

New terminals.
Caps.
Some more mods to be done before pwr up

Hi to all,
here I share my realization of the DENON PMA-SA1.
Input stage and VAS are Sony's style circuits.

The output stage is a UHC Mos Bootstrapped Cascode as in DENON top amplifiers.

Some of my DIY amplifiers - preamp, poweramp and phono preamp.

My mosfet amplifier is driving the Visaton BG20 fullrange speaker.

 

[dadod]

Line/phone preamp with no global negative feedback. Volume control after gain block(4x) and before output buffer. Could drive low impedance headphones

My 2x250W/4ohm BJT amplifier based on @DouglasSelf blameless topology. More here:

[dadod]

200W/4ohm vmosfet Class A (two OPS, low voltage Class A and high voltage Class B).

Hey, below is my recently built amp with autotransformers 2x300W into 2/4/8R load...

THD: 0,001% at low power and about 0,005% at full power.
SR: 25V/us
FR: 3Hz-160kHz /-3dB full power low frequency limit is around 20Hz, below that output cores saturates

I have a soft spot for mosfet, ready to transform the power supply independent split power amplifier
