I have some, but yes matched pairs would work.

Nelson Pass and others prefer the silks for measurement reasons (and listening). There are test results over at DIYaudio somewhere... I actually use Black Gates before regulators, so my feelings are hurt

yes, they give the real stuff a bad name. Look for the old yellow Philips / Siemens KS box caps, with *real* leads. The other stuff you have to be very careful not to damage them, and honestly I'm not sure how you tell if you did indeed damage them. There's also a company called LCR (?) that sells grey box caps that are in current production. I've only found them through Farnell.

looks like the identity of certain caps was obscured to protect the innocent:

here ya go: :) High End Audio - Electrolytic capacitors

here are the parts I'm planning on offering from Digikey. Let me know what you guys think, as I'd like to get this ready to go once the boards arrive. Please let me know of your interest here or via PM: C10 (2) P3874-ND (was P3124-ND) 0.120uF C11 (2) P3876-ND (was P3154-ND) 0.150uF C12 (2) P3864-ND (was P3473-ND) 0.047uF C13 (2) P3884-ND (was P3334-ND) 0.330uF C4,6 (4) P3154-ND heat sink (2) HS133-ND Q2-Q5,Q12 (10) ZTX450-ND Q1 (2) IRF9610PBF-ND D1 (2) 1N5346BRLGOSCT-ND R2,3 (4) P4.7W-3BK-ND$2.38 / 5 bridge (2) 26MB10A-ND fuse (1) 486-1234-ND IEC (1) 486-1084-ND SIP sockets (12) A461-ND (for loading resistors and capacitors) jumper blocks (12) ED7264-ND (for loading resistors and capacitors) jumpers (6) A26228-ND (for loading resistors and capacitors) standoffs (0/4) 1825K-ND (2.5" only for those stacking boards) standoffs (4/8) 8414K-ND (4 for those stacking boards, 8 for others) if you are in need of extra capacitors for capacitive loading, please let me know. Total for above is $78.50. The difference in standoffs is about a wash, and one price simplifies things. This doesn't include shipping (but it does include sales tax), but we can settle up on that later. Then we have 2 options for caps: C1,2,3,PSU ( P6946-ND C5,7,8,15 ( P11249-ND [/code] Total for this option is $75. Then the other option for those looking to cut some corners (less capacitance, default part recommendations from the guide). [code] C1,C2,C3 (6) P6939-ND C5,7,8,15 ( P5557-ND Total is $38. This leaves the JFETs, coupling capacitors, capacitor clamps for unregulated PSU cap, RCA jacks, earth binding post, and resistors.

what is the function of the caps you're interested in? coupling, bypass, rail capacitance, timing, etc. for me, anything that involves styroflex / polystyrene Also, has anyone tried using PTFE trimmers in place of small silver micas in the pF range?

if you're interested in the boards, I can give you contact information on who to talk with, but the order has been placed so you'll have to fend for yourself in terms of overseas shipping. Orders for the toroids and cases have been placed, so you're on your own there. You can benefit for the rest of the group buys, just let me know.

non-switched I'd assume? I'm curious why there isn't an output selector... so I see your confusion.

I don't listen to gear these days, I just look at it

meh.. I'd rather just have a big ass isolation transformer and bits of AC filtering and EMI/RFI filtering in each component... if I really cared, I'd get a NEMA class surge protector and be done with it.

ah.. just unplug it before the storms? I don't see why people recommend a surge protector at all...

why use a surge protector at all? why not use fast blow fuses with some sort of inrush limiting?

I just bought a large lot of 0.015uF Russian FT-1 teflon caps to use to bypass the output caps. I'll include these with those who are interested in the kit (basic or no-so-basic).

ok, I need a quick sanity check. Amplifier input impedance is somewhat arbitrary for the Pass F4, but let's assume 47k, which is the default. Output impedance of my preamp is 100k, with coupling capacitor. My soon-to-be speakers have a f3 of 40 Hz and the driver I'm going to use in my future-to-be speakers has a fs of 48 Hz (it's a 15 cm driver), f3 undecided. I'm considering a 3uF capacitor with a small bypass, maybe 10nF. So, I'm getting 1/(pi*47k||100k*3uF), or fc = 1.66Hz. Opinions?

nice. what are the loading recommendations for this? 1k or so?

what, they invented the fucking thing? I'm not going to touch another Single Power amp whether it's on or off until I've seen what's inside.

The 6016 is $36.97 in natural, $41.95 in black plus shipping.

here are the quotes for the Y236007 5 pcs: $18.48 each + $13-ish shipping ($21 each) I think this is a good enough price point to move on, so I'll send some PMs out to people who expressed interested in a parts kit.

hum a hum a hum... I think I'll be trying something from here: Wolgram Products- Sescom Enclosures prices are right and they look decent to boot!

heh. I just was on their site did you purchase them direct? There was another company back that I found that made cases that look like the little creek headphone amplifiers, and like the Whest phono preamps, but I cannot seem to find them now.. oh well. edit: found 'em: www.nutech-eng.com

any recommendations on a nice little case that could fit a single PCB? They are 7"x5"x~3" high. The largest Hammond is oh so close..

agreed...

I plan on using a chassis mount rectifier bridge and then a single cap which will be mounted with a clamp. I'll probably leave out the AC filtering. I contacted an individual who sells Pearl kits asking for a few psu boards, and he didn't reply to me
