Clone Goldmund Amplifier

[hien.t.nguyen]

Thank you for the explanations!

I agree it looks similar to Telos 250. Why did you not use the cascoded output stage from the Telos 5000, it suppose to produce less distortion?

There are clone Goldmund amplifier T5000, have not my design

I try done the same completely.😀

 

[hien.t.nguyen]

I make this amplifier according to the schematic of the Goldmund Telos
5000 amplifier
I try not changed much compared to the original design
Some positions do not find the original design of components, I
replaced the equivalent.

This is

1. Power Diode STTH 6102 = STTH 6002
2. Mosfet: 10N20 = 2SK2221
10P20 = 2SJ352
3. CCS: ADR445BRZ (5V + /-2mV) = AD586 (5V + /-2mV)

4. Not DAC, DAC original design
5. Stereo, the original design is BTL Monoblock
6. Volume relay 5 steps original design control by remote, I used
ALPS 27 - not remote,not CPU,...

Did you make this case or did you buy it? IF purchased, where and what was the cost?

V2 just has 1 heatsink on the back? I personally think 2 heatsinks on both sides is a nicer layout and look better ... Look more "bear" as we often say lol.

How much did you spend to construct this masterpiece?

I need a the chassis, you can sell to me?

Conratulation Hien!
I have a picture about this Goldmund Clone in first time show:
A doctor checking very carefully before allow the Amp run

I think heatsink's V2 too small. maybe it is not enough. V1 has big heating.

Hi Mr.AirPower,

Could you share with us some more pictures of the system used to test this amp and how did this amp sound on that system?

Thanks,

Really?
But i knew that mr Ultraline had sold it to a member of VNAV and you can set up it with your system in only 15 days to review.😀

I knew that at least two copies of V1 are in service so far... A fat guy was testing it in comparison with a Tact amp, while another amplifier was on high power at nite.
