My Goldmund transistors are mpsa42/92. I am attaching the Goldmund Umun schematic..
Alex! From 2013 to 2022 do you think it is necessary to make any updates?
What are the electrical specs of your power supply?
They are great devices - if you use them right. They're great as drivers in an EF2/EF3. Some are using them as cascoding-devices in combination with low Cob/Cre semis in the VAS (even Marantz in some bolide-style integrated amps). But personally I wouldn't use them plain in this specific VAS. Even the 340/350 are better for this here.
BTW: Your 2SC3421/2SA1358 are now called TTC004/TTA004 with the same specs and are widely available through the big distributors... No need to buy some out of questionable sources...
Thank you nfsgame In the diagram 2sc3421 2sa1358 these are also available I am undecided
I will use Mosfet power transistors 2sk176 2sj56 and I have 1 pair for each channel.

hello,
I have several questions about the GM29.
What does the HM3S reference correspond to?
Is it a class A or AB originally?
Thank you
PS : I didn't know if I should open a new thread.
