Some fully built SMD Cap Multiplier modules, design by Mark Johnson, PCB layouts by Prasi. These little supplies are excellent and I'm using them in my Whammy and Marsh HPA. These are not adjustable regs, the dropout is only a couple of volts and the trimmer only adjusts by a volt or so to fine tune the rails.
details of the circuit and boards are here from post #613 - Juma's Easy-Peasy Capacitance Multiplier
These have been carefully built with matched SMD transistors, MELF 0204 resistors, nichicon/Panasonic caps. Complete with DF01 rectifiers they are stand alone dual supplies up to 35V
One pair of Low power SMD Cap MX modules are available. £35 a pair - see pics in post #9
-----------------
ONE MID POWER SUPPLY IS now AVAILABLE - fully loaded and operational with ultra premium parts. Please see pics in post #9 - LT4320 Mosfet bridge with 4 x UKW 4700uF CRC filter into Cap MX. Superb quiet supply with lower dropout. This was my golden reference perfectly built with selected Toshiba transistors - £55 plus shipping
Two mid power MX PCB's with SMD parts fitted, no other parts - £5 each
[/B]
-------------------
Prasi design, one pair LT4320 bridge CRC power supply PCB's with extra Cap MX boards. Superb quality boards by Prasi, the MX PCB's can go between the caps or at the output for CRC -> MX
£15 shipping £5

What size SMDs are on the cap MX boards? I only really go down to 0402 and only then if I have to 0603-1206 is my happy place. would be interested in some pcbs but only if I can actually populate them.
You will have no problem, all packages on both size boards are 1210 or larger. I used 0204 MELF resistors and they fit perfectly.
If you want the smaller low power PCB's I only have a couple left but the Gerbers are on the thread.
If you want the mid power LT4320 boards then I have plenty 😉
0402 is about the size of bacteria, I could never see one of those.
One pair low power and one mid power modules sold.
PCB's of the mid power LT4320 Cap MX bridge boards available for free or with SMD mounted.
