Tnx 6L6. Yes it is exacly that. It is alot to choose from. The hard part is to choose which on to go for 😀
Maybe I missed the PSU proposed by Mark Johnson, everybody's is talking about it, someone link it, please.
Another Wayne BA 2018 linestage is playing music...
Have got my build powered on and playing music...
Initial impressions are very positive.
Thanks to Wayne for making the design available for the DIY community. My thanks also to the folks who have contributed to this thread making the build easier for me, and of course to 6L6! 🙂
Some details of the build:
Glassware Dual/Bipolar Low-voltage regulated PSU running at +/-18V DC
Antek 2 x18V AC 50VA transformer
DACT type 50K potentiometer from Ebay
Gotham GAC-2 microphone cable for input
Mogami W2314 for other signal cables

If you like the power supply Wayne designed for his Whammy, and don't mind having the PCB fabricated, you can use my gerber files located in post #1200 of this thread.

Alternatively, member Gaz2613 has his own adaptation of that circuit. He may have some boards available for sale and he's over on your side of the pond.

Hi, got a couple of questions that I know have been answered before but can't find where.
1. Which of the small blue caps is the 10PF as I can't read the text on them?
2. Do I need to set the pots to a set value before installation?
Cheers all.

My Mega328 component tester happily tests 10pF capacitors and reports "10pF" on its LCD screen. Have you tried one of those?

The 10pF are on tape, the 5pF are loose.
No.
The Mega328 device Mark linked to is an incredibly useful tool and I highly recommend it. Particularly as they are very inexpensive for what they do.

could not get my head around the schematic until I found this
Ground rules: earth, chassis, and signal ground
Different symbols, different interpretations
Well, Wayne said: "Also we see that the chassis is directly (and with heavy wire) attached to the earth ground of the AC line and that the signal ground of the circuit is attached to chassis through a high current bridge rectifier as shown."
If it helps, 6L6 included another sketch in his thread:

A quick question on the proper transformer for the Glassware dual regulated PS - +/- 18V supply. Looking at the previous page ZMan01 is using an Antek transformer with dual 18v secondaries - would a transformer with dual 15v secondaries also work?
