Hmmm....it seems most problems are on the input stage.Probably very sensitive.... but using galvanic separation audio transformers (high quality) should not be any issues....

Will be nice to hear some sugestions from Andrej...

Destroys all dynamics. Very booring sound.
+1.
Renders the entire idea of having a good amp pointless.
Mhhh, that’s your opinion, not an absolute truth... or are all recordings from the pre digital era pointless? Magnetic tape changes the dynamics of music much more than a good transformer.+1.

Transformers can be nearly undetectable. I guess an amp that destroys itself all the time is pointless.
Ah sorry, misunderstood those comments... I don’t know those specific transformers... but like the large interstage lundahls.

This one is really good :

If one is thinking about expensive input TX, why not think about expensive but great (not) sounding TVC's? 😉

Hello, do you have the reference for this 15k smd resistance (1502) ?

Thanks

Thanks
Short update, MELF resistors almost all reels here, other SMD reels on order - coming soon. Don't want let anything to a manufacturer's lucky chance, all materials placed on modules will be 100% approved by me. In the mean time we have a lot of fun in our shop.
Cheers L.C.

Hello LC, i would like using 1.2 version with lower supply, so I need to decrease the resistance on CSS, maybe adding 15k in parallel, could you give me the reference ?
Thanks

At +/-60 V PSU measure the voltage drop on 15 k resistor, calculate CCS current.Hello LC, i would like using 1.2 version with lower supply, so I need to decrease the resistance on CSS, maybe adding 15k in parallel, could you give me the reference ?

At lower PSU voltage set the resistor value to get the same CCS current.

It will be a bloody magical moment when you fix my amp module like you said you would about 18 months ago 😡
Plan your visit
We have four Magico pairs prepared for your listening experience:
- M3
- S3 Mk II
- S1 Mk II
- A3
connected to our First One electronics.
All warmly invited to visit us at UBIQ AUDIO in Ljubljana until April the 6th, welcome. 😉

We agreed in exchange plan, gathering reels and reels ... soon
Thought you know. "Duelund Coherent Audio"DCA, some kind of an avenger? 😀
