F5 power amplifier

General question, where can we get 2sk370 and 2sj108?

I found mine on ebay shipping from China with Guaranteed +/-3% Idss. Not cheap buy cheaper than the techdiy guy. I think it was 14.99 plus shipping of about $5 for 8 of them, 4 of each.

ps I checked both variations on Mouser, Digikey, Avnet, Arrow, and Newark. Nothing. I bet a lot of people bought from Digikey and it seems that people tend to buy dozens to hundreds of them. I bet if you wait a while they will be back in stock. But then again you could be at home with a fully assembled amp with Original NP PassDIY boards and be missing 2 parts :)

Babo You,

just think, you could just as well have been guiding the construction of Abramovich's new +500ft and +$300M supertoy yacht Eclipse at the Blohm&V. yard in Hamburg.
A former class mate is part of the drawing team there, my sheep-design professor was the No1 honcho at B&V for quite some time.
(on second thought, a wild one such as You would likely be cuffed and arrested at the Hamburg Reeperbahn every night)

I'll take that as a no? :rolleyes:


you can build most of the power supply on the terminals of the caps. Literally lay it out like you see in the PS schematics (which are in the user manual for the F5, available at firstwatt.com in the product section)

I find power supplies easier to build than almost any other part of amps, so I'll pop in and do whatever I can to help you.

There's a saying overhere, updated to more fashionista times it's like : if you offer them a finger they'll take your pyjamas.

If i read just a single pretty plea for matched output pairs you can tell Patrick i bungeed over the balcony.

Aah, the joys of not having to have power amps in the same room anymore, which supercharger will humvee there at yonder side of the wall ?

Vince,

would you like me to feed it some Viagra and show you twins ?
Granted, it's a mere 10" tall and handles less than 2kW with twin screw superchargers, there's a lot of that stuff offered frequently overhere.

If you can't stand the $/gallon gas rate any longer, ask Babo to send you some crude, looks like he has plenty. :clown:

Here Babo, give Luca Bassani a call :VL-Tennis-Carrier
