Thanks Mr. Jacco... There are a bit of interesting things on Ebay these days:

Nope, but Mr Oomis is from my home town, i used to buy parts in his store.
Interesting prices indeed, cheaper than buying new limited values LCR styrenes at Farnell/Newark.

hm, on the 20n5 RIFA PFE225 I can negotiate down to $55.00 plus S&H $9.90 for 50pcc and $100.00 plus S&H $14.90 for 100pcs. I'm haunted my the sound of polystyrene in RIAA filters now.. seems like a good deal, no? 20n5 is almost as large as they get in the PFE225 line it seems... not that I want to build a third phono stage... but anyways.
Consider that LCR in Wales and Reliable-Cap in Cali are about the only ones left who still have polystyrene foil to manufacture such capacitors, while it lasts.
Boxed 63V types cost close to twice as much as a 160V axial counterpart from the same manufacturer.
Converted to today's price level, a 20n5 for example would be around $5 each minimum.
Epoxy resin encapsulated foil caps virtually live forever, either $1 or $1.20 a cap is a bargain if you can live with 63V, compared to RelCap RT rates.
(Wonder-C/REL RT are great caps but even the 100V type has a lousy accuracy, which limits their practical use to bypassing and with a value of up to 3uF as coupling-c imo)

An externally hosted image should be here but it was not working when we last tested it.

Q1,2,3,4,5,8 - any decent little plastic TO92 bjt thingie - hehe - even Papa's crummy ZTX are good enough
Q6,7 - any decent bjt in TO-126/SOT32 case
'Vitty will tell ya niponese numeros ......
Depends how high you intend to bias the CCS, the range for R12+P2 is ~ 45mA-130mA.
At a low bias current level, a TO-126 wouldn't even require a heatsink.
If it were a cheapo circuit and biased at <60mA, 190MHz Phily BD135/139 would do, any other BD manufacture sucks.(see comments of Mr Creek Nikitin)
The dual triode mini a-la ECC82 at the input makes it a non-cheapo anyway, Toshiba TO-126 nicies would be 2SC2824 or 2SC3421.
Personally, i would likely try to shove a 2SC5171 through the TO-126 lead spacing holes, duh.

I will keep working to try to please the frugal and intense ZM.
naah ....... I'm just (!!) stubborn
I hate to pay for finest FiFi fog ...
been there .....
or just use two XLR cable connectors , with shorted pins 1&3 ;
these are certainly fancy , and still useful later ....

no I am using F4 with XLR with vampire male with RCA stuck in the end, and internally shorted. Of course with Pumpie, I am not sure I want to build in RCA set for CD player, or just use a shorted homebrew XLR to RCA cable(think that's what your saying). Just thought a good jumper would do the trick, without being weird. I also assume there is no penalty for dual XLR outs here....But will re-read cookbook later.
I'm tired. Your simply an insomniac.
