Just use first rate MilMax IC socket, gold plated, high insertion force. TO-92 fits perfectly in these. I used them years ago in my PassLabs Xono and never had a problem. I used them now with all matched parts. On my Pear 1 I had a burned FET from one of the QUAD (certainly from a very bad spark I heard with a defective tonearm wire on my Thorens TD124. It was then easy to find a match from my stock of FET. In circuit matching is also the best.

I bought 0.1% 10 ohms resistors for the matched Quad.

Default Film caps

Can anyone recommend a source for the .01uf, .1uf, .033uf film caps as listed in the parts list for the Pearl 2 ? The suppliers that I know of all show no stock, with lead times of many weeks.

Thanks,
George

Wayne used some Wimas MKP and maybe he can lead to some good source, but did you try Mouser, Digikey or Newark ?

Best regards,

Hi nar, Thanks for the reply.

I've searched Mouser, Digikey, Allied, Newark & RS Components with no luck.

Maybe I'll look into adapting some of the surface mount 2% film caps that are available.

you could try TAW down in Burbank

Capacitors, Resistors, Connectors, LED, Varistors from WIMA, AOP, PIHER, NEMCO, FISHER, CAPAX, ARCO, SAURO, SFI

mouser has FKP 0.01 in 5% and 1%, they have 511 of the FKP 0.033 in stock, and they have 594-2222-417-41004 with 10mm lead spacing

I used all MKP1837 from parts connextion, but it looks like the .1 are out. They don't fit in well, but can fit if you work with the leads a bit.

Using a plain Denon 103 cartridge, the phono rig with my Pearl 2 sounds totally nonagressive, sweet and detailed, with a good soundstage. Some of this the nature of the cartridge character for sure.


I used a Salas shunt Reg for the power supply. (attached)

In order to achieve good gain, decreasing R14 did not add much gain, but replacing R15 jumper with a 1k resistor did give more gain. It could still use a bit more.

Algar Emi, thanks for that wonderful parts list. For those of you looking for parts, I'm getting almost everything from mouser. It's all there, just have to look hard enough.

Algar, the transformer is a 2x22VAC... 30 V is after rectification and filtering. You have it down as 30VAC in the parts list.

One question: For LM7824, will this work as a replacement?
MC7824ACTG ON Semiconductor Linear Regulators - Standard

Here's the part number if the link doesnt work: 863-MC7824ACTG
Mouser is out of LM7824 for now.
