The only ones in your list currently available (without contortions) are the Linear Systems LSK489 / LSJ689. These are available from Trendsetter in the US. I'm not sure who in Europe carries them. You didn't indicate where you are, but judging by the Farnell I assumed Europe.

I noticed that you didn't tap the holes in the bracket for the screws? Any reason? Seems better to me than using nuts on the bottom. Also, I don't believe the metal rings on most of Kevin's boards are connected to anything.

Oh no no no... a GE Wildcat is what u really need. I can personally vouch for its awesomeness! https://www.ebay.com/itm/General-Electric-Wildcat-Vintage-GE-Turntable-Portable-Record-Player-Working-Tan/324509893961?hash=item4b8e4c0549:g:AbIAAOSwXh5gRCvK

Happy belated Birthday!

Schubert?

I probably have extras. Let me check. The gerbers for the ones I did aren't on Kevin's site. I've attached them here. THAT340-TO71.zip

Most kind of you. Yes, I would like a pair. PM me and we can discuss.

Adapter boards that I layed out and were in one of the GBs. I think you could just plug them into a 14 pin socket with no lead bending, but if I recall correctly, one of the JFETs would be backwards. No big deal on the Toshibas, at least according to John Curl. I presume the Linear Systems would be OK as well.

Not sure who you are asking, but no, I don't have any, and they probably would not be for sale if I did.

When I used the Linear duals, because of cost, I didn't bother matching them N to P. Kevin has said the CCS takes care of it anyway. If doing singles, if you can get them matched including N-P without a huge premium, I'd do it.

Cool. Thanks Kevin!

Unclear. Going back in the thread, I had posted this, as the schematics I have don't appear to have this fix in place. Shortly after this post, you released new gerbers including all fixes. However, there was an error with a 10K resistor connecting to a device emitter instead of the base. Not sure whether the fixes mentioned were in only referring to this or also included the servo fix. I don't see a pair of 15K resistors, as were used in the CFA2 fix, on the gerbers.

@kevin gilmoreDo the current gerbers (cfp3rs and cfp3rss) have the servo/current mirror correction done to the CFP2 on them? Or don't they need it? Thanks!

Does anyone have a pair of CFP3 boards they want to get rid of? Also, I see two sets of Gerbers: cfp3rs and cfp3rss. Is the difference the revised servo/current mirror? I'm assuming the cfp3rss is the most recent? Thanks!

Happy Birthday Nate!

Yes, not cheap, but considering it is a matched quad, approx. $11@. And generally unobtanium. The diyaudio store charges $39 for a similar matched quad of the Linear Systems devices (2 N, 2 P).

^ Reputable seller of genuine devices.

Is the one on the right a 2U? Looks to be 1U from the pic. The SlimLine have 10mm sides which would be sufficient for heatsinking for many applications.

Happy Birthday Craig!

The LSJ109 is (was?) a dual JFET, but not in the same package as the Toshibas were. For thru-hole, it is available as a TO71 can package with 6 leads. It seems as though these are either discontinued or just not available. Your alternatives are to use the LSK489 / LSJ689, or use the singles. The 489/689 is what I have used. The diyaudio store sometimes has the singles: https://diyaudiostore.com/collections/parts/products/linear-systems-matched-jfets

Sound-wise, any of the JFET options are preferred. If you can find them, the Toshibas would probably be preferred (2SJ / 2SK parts). I have used the Linear Systems LSK489 / LSJ689 and didn't notice a difference from the Toshiba devices, but I have read that some prefer the Toshiba. The BJT devices (2SA/2SC or the THAT part) to me don't sound as good. Not bad, but not as good. And that is with 10K pots. I think the 2SA / 2SC sounds a little better than the THAT part, but not up to the level of the JFETs.

When I look at the KBP201G on mouser.at, it shows 429 available (same as Mouser US)?

How about 621-KBP201G (Mouser PN). Haven't tried it but same specs. These bridge rectifiers are common parts and shouldn't be a problem to replace. Also a Rectron MDA201G would be another one to look at. 2A 100V bridge rectifier in an appropriate case/footprint and pinout.

Happy Birthday Naaman!
