I have built the NJFET phono pre by Salas and I can say that even with modest components and on perfboard it performs very well, as many other builders would agree. The thread is long but there is a PDF summary (actually there are a few) that covers all the basics. Check Salas's evolution/update link on the first post to take you to the latest "basic" version of the circuit.

Salas also has a shunt reg that is recommended.

Both have single sided PCB files around too.

Cheers,
Tani.

FWIW, I use one of these Amana non-ferrous blades for aluminum. The triple chip and negative hook angle leave a mirror fine edge.
I cant tell you exactly what the temp is as I dont have a IR thermo. I did run it for 8hrs biased at .65 and the whole case was cozy warm to the touch, not uncomfortable at all.. When I touched the mosfets they felt about the same temp as the case.. So far so good.....
Thanks for the tip on the blade

Nice to see someone finally make that style of case.
Where did you pickup the tubing and did you use any thermo grease between the tubing and sidewalls?

Thx,

Vince
The tubing came from Online metals.com
Yes a thin line of thermal grease squeezes out nicely when the tube is tightened down

Default A Different Zen V9

After smoking my V9 circuit a couple of years ago I tried again and this time it worked so I made a decent case for it.

"Decent" - a word that'd be at the bottom of the scale of possible descriptions for what you've done. Wow ...

Give us Hi-res shots, pretty please, with sugar on top!

The restrictions are very lax.
There is a Thread about downloading appropriate sized pics.

It depends on the detail you want us to see.
