Plethora of Pinjatas / SET P amp(s)

[Zen Mod]

same SL OS both

M25 - SE input only, autoformer based FE, No NFB, gain either 4 (Cinemag, Jensen classic repeaters) or 6 (Edcor 600:15K), mild THD, dominant 2nd neg

PoP - active FE, both SE and Bal input, NFB yes, gain - forgot ........ aha - 100K/10K, loow THD, dominant 2nd neg

sound - all my amps are sounding the same

Well, I'm thinking of one or other, Lord knows I need another.

What other output Mosfets can be used in this schematic? TTC5200/TTA1943? FQA40N25/FQA36P15? Or something better?

How to get these pcb-s and matched 2SK2145BL ?

 

[Zen Mod]

other OS parts - they will work, but with slight difference, if there is a difference in xconductance, comparing to originally used

slight - no night and day

though, clever to use mosfets in output, as is constructed ........... TTC/TTA are bipolars

availability - you're practically just one personal message away of knowing how

Now, he is in for it! I see him getting many packs from behind Iron Curtain!

Which case you recommend for XA252 PoP?

 

[Zen Mod]

4U/400 Modu is natural one for all my small amps

don't forget - they all are sounding the same ........ that's why same adequate case

A close friend of mine liked the Mini so much that he wanted one too.
I hope he will like the outcome 😎

 

[Zen Mod]

matter of principle - if sending wires though metal plate, always do it in "natural pair through one hole" fashion, using grommets

example: [L & N] wire through same grommet-ed hole

example 2: [+, GND, -] through same grommet-ed hole

btw. which amp is that?

if PoP, I'm glad seeing someone else's pcbs

I'm famous!!

 

[schultzsch]

Yes, it is the PoP.. I call it Mini
