help finding some components

[mastermachetier]

Hello I am putting together parts for a few pedals. There are a few i am having some issues finding parts for. I have listed them below and the associated pedal. I'd appreciate any help !

Tone Vendor	5u, OC81D
Twin Face	20u, AC128
SunFlower	NKT275
Terrarium	L78L054
kliche mini	GE, B100K Dual

I am open to alternatives

Hiya i got Most of my Kliche parts from here

16mm Dual Gang Potentiometer - Short PCB Leg

Top Quality Parts for Guitar Effects Pedals and DIY Music Devices. Knobs, Pots, Switches, Kits, LEDs, Enclosures, Jacks, Wire, Resistors, Capacitors, Semiconductors

stompboxparts.com

Use the pulldown u will see the B100k, Min order 3 tho so its $3.00
For the Ge i used 2 1N34A Min Order is 4 of them thats $4.00 saw in a post some 1 also used a D9K diode

Use 4.7u for Tone Vendor. 22u for Twin face.

Germanium transistors can be found at smallbear elec. The path of least resistance (to me, since I didn't have equipment to test germanium transistors) was to buy their matched sets, which they sell specifically for tonebenders and fuzz faces. They probably won't be the same part numbers, but will work well in these fuzzes. They're a bit pricer to buy matched because you're paying for them to sort and select them. Alternately, If you know how to measure the gain and leakage you can buy a bunch of cheaper ones and select them yourself.

Smallbear’s been out of matched sets of germanium transistors for a while, anyone know what’s up?

(I’ve started buying bulk lots from overseas and testing and sorting them, and it’s *just* enough a pain that I can say Smallbear’s services are much appreciated)

Oh, that's a bummer. Maybe they got swamped.

I suspect that like everyone else, the Pandemic has upset their supply chain.

Which transistors are you buying abroad and where ?

Which transistors are you buying abroad and where ?

Sure! I've been buying on eBay. I'm pretty sure at this point in history, most lots of germaniums have been picked over for the "good" ones, so I'm not trying to go broke buying the biggest lots, only spending a few bucks so I don't feel bad if I get a batch of duds.

from nati.99.electronics I've gotten two batches of MP20s, none were duds and all clocked in around 60-70 hFE with near-negligible leakage and I've spot-checked a few in circuits, sounded great. Wouldn't hesitate to buy from again, they've got *lots* of goodies.

from sp9tnm I've gotten a 10-pack each of ASY33S, ASY34S, and ASY37S (they accepted my $5 offer for each, so $12 shipped, $1.20 per transistor I was willing to swallow). No duds, but gains and leakages were *all* over the place; I was able to suss out a few Fuzz Face pairs between the lots, some of the ASY37s were decently leaky and had gains above 200 and worked well in Tone Benders. The rest are neither here nor there (didn't really fall in the "classic" ranges for RangeMasters, Fuzz Faces, or Benders, but still work and will always be worth trying out), but it's nice to have spares and alts to play around with.

I've bought 50 1T308Vs, about 1 in 4 were duds, the rest tested okay but some are really hissy once you get them in circuit. Won't link to the seller because I probably won't buy from them again.

I don't believe that it's an issue of stock. It's a labor-intensive process to match the transistors and provide the biasing resistors. Since everything is taking longer than normal right now, I believe they've suspended the service to help free up time for order fulfillment.

The take-aways from Manfesto's post are:

If you buy transistors on eBay,

1. Be prepared to test and sort them.
2. Expect to get a few duds.
3. Don't spend more than you wish to lose.

There are some decent deals out there, but there are also some shit parts. The best deal I got on eBay was 100 2N1308s for about $2 each. They were all legit. 8 of them were dead. All the rest had gain over 150, some over 250. Leakage varied considerably.

Can get the AC128s from Banzai and pick your hfe range too, that's where I got mine and they worked great

Not sure if PedalPCB can confirm with a build on their end, but a couple of ppl on this forum have had problems with different AC128 Transistors biasing correctly on the Twin Face. Don't repeat my mistake and buy the wrong ones.
