Got a package today from Mike/TEABAG!

Excellent quality PCBs - thick like John Broskie's (TUBECAD)!

Now to get those large heatsinks and as nice a set 10uF caps as I can afford!!!

Thanks very much to Michael for his work. You have done very well and I am very satisfied.

The rest of you should be just as pleased as I soon.

And most of all thanks to Mr. Salas for his willingness to use his fine brain for such an absurd but noble hobby.

Dimensions of Salas SSHV2 PCB

Hi Tea-Bag,

I might be interested buying 2 such PCB's of the Salas SSHV2 if still available. However can you give me the exact dimensions L * W of the PCB first? Thank you

This is a group buy for the purchase of the second generation Salas Shunt High Voltage Regulator.

It's a newer design that Salas did, with CRT brilliant layout work and a bunch of us prototyped over the holiday season. We had a zero percent failure rate of setups amongst us. (Which I consider great, as most of my work , well needs work)


Let's get to the point.
The board is $12 USD.
Shipping is $6 for up to 3 boards
Shipping is $8 for up to 6 boards.
Some may note the increase US has to incur with our local post office. Sorry

Mini-Kits will be available. The cost is higher than I wanted them to be - so I split them in two.

One will include the transistors, diodes and LED, mica and washer. 3 2SK117GRs will be provided for best matching per kit.

The other will include the resistors and the potentiometer Vishay T93YA model which is 100ppm. The rest of the resistors are lower PPM as reasonable. This is $8.00. These of course are optional purchases, and feel free to roll your favorites here, although I recommend a low PPM 68K.



Heatsinks, caps and Molex connectors are not included - although if there is enough strife, we can consider a GB for those as well

Again a disclaimer - this is the most dangerous product I have shipped yet. Failure to respect the high voltage of the product can have deadly consequences. This is not a beginners project!

The full specifications are in the PDF file. (attached as zip)



The google spreadsheet needs to be completed with your username and includes paypal payment details. Please don't post that address here.

The GB ends on ~11/04/12/U]. This will be a quick turnaround GB so those who have been waiting for a while can get there hands on these. Payment can be taken immediately.

Extra parts in the kit?

I notice there are extra LEDs and some of the small signal FETs.

Are these in case we blow something up?


When it comes to the LED will one of them give a better result for voltage desired?

If this has been explained already please forgive me. But, point me to the thread, please.

Thanks,
