Hi, mcmahon... here are some inexpensive devices I have had good luck with...


Input stages / general small signal amplification (to-92)..
BC556/546 good for little amps (60v) 2sc1845/2sa992 (100v)
bigger amps - and ksa 92/94 (300v). all have Ft of 100mhz+
and Cob of 2-6pf (fast devices) making them useful for just
about anything as well as being cheap ,$.09 to .15 apiece :) .

Drivers/ medium power devices .. (to-126/220)
MJE 340/350 - good general purpose high voltage devices,
a little slow , but widely available.
Ksa-2sa/c.. 1381/ 3503 .. killer VAS devices...
MJE 15032/33 - 2SC4793/2sa1837 ...drivers, 2sc/a's are faster.

Power devices - (to-3 / to-3p)

Mjl4281_4302 / njw0281-0302 /Mj15022-25
njw0281-0302 are real cheap $1.40 ...
FJL/P fairchild devices are available ,too..
Everybody seems to have a preferance , but I have noticed
output device choice has little effect on sound.

Most are available from Mouser , MCM , parts express.
Local distributers and Radio shack suck , more expensive
floor sweepings... garbage..

Hi

I quite often use RS's vero-boards and accessories for proto-typing.:)

It depends on what level of "hobbyist" you intend to be. I use a lot of SMD parts, they are good quality and generally cheap.:p You can easily use SOT-23 and 0603 size components with the vero-board. It takes a steady hand though.:)

Some of my circuits (ex 1, ex 2, ex 3, ex 4) have a few more parts than most here would tolerate, but to each his own.:rolleyes: A small assortment of small signal J-fets wouldn’t be a bad order either.:)

KSA2690/KSC1220 are useful as drivers, or maybe VAS........cascode. Their cost efficient too.:)

I can vouch for the THAT corp. matched transistors arrays, THAT 200/320/340 if you can sling the price.


Mostly, have fun!

:)
