You just need a 'POWER BULGE' as was fitted to '70s modded cars !

The 2sk389's are matched pair (one die)
was going to use them in a RIAA circiut
I also have some MAT02's /3's (sample's hint)
BC550's are good low noise tranny's and cheap too😀
There is a simple circuit for matching fet's on this site
i'll see if i can find it

Cor ! your posted site takes me back many years !
My first computer project at Uni was to write a program, in Algol, to calculate the values around this circuit. A large stack of punched cards about 20cm tall !

Or rays tube state for his 150v transformer😀

ps ray did you get the cover on??😀

Now there's a thread all to itself
but i did read Jocko likes coloured ferrite beads

A little better but furry dice hanging off vol knob will improve detail no end.

Nostalgia.....😀

Yep, the cover fits. No need for a bulge here 🙂

Currently they are 56V 12000uF ELNA 'FOR AUDIO' caps.
They are about 1/3rd the size so these ones will have too be mounted on back panel if there is enough room.

Hi Allan,
Cool links, thanks! I haven't been into solid state lately (gross understatement...) so these are very helpful.
I spent four hours listening last night, to determine the difference between two players (opamps vs. passive + transistor stage) and the winner is absolutely the transistor stage. The soundstage is more accurate, with better to pinpoint instruments. I thought I had lost some air or space, but it's there when it is supposed to be. With the opamps there seems to be more space all the time, and that sounds very cool at first. But it seems to lead to somekind of smearing in the soundstage, which makes everything less easy to pinpoint (am I still making sense???).
Regards,
Ray.

Hm, figured something like that. I put some on the breadboard last night and three of the four FET's are almost equal. Number four is way off
