The SLB (Smooth Like Butter) Active Rect/CRC/Cap Mx Class A Power Supply GB

[xrk971]

Dual secondary is the design. Although I am not sure if a center tapped wouldn’t work if you made the center tapped shared between 2 of the inputs? Maybe someone who may have done this can comment.

There’s a discussion on that here and does appear possible, but ideally - dual secondaries will be the way to go.

Center Tap vs Dual Secondaries

The transformer will have to be wound Bi-Filar. If there is a voltage difference between the two windings, there will be an unbalance in the power supply.

Hi X,

My apologies, did not think to include my details. Stupid on my part. Got your invoice, and finally got the payment through to you. My bank declined the card three times. Ended up having to exit out of the browser, clearing the cache junk, before PPal would process the payment via my bank. Looks like my bank is trying to control my spending, which is just not possible.

Hah! I'm still waiting for an indictment on money laundering charges when my bank tips off the authorities about the incredible number of shipping fees I pay to DigiKey and Mouser.

[surfatwork]

Paid. sorry, was travelling.
have sent you a PM with the shipping address. Please dont send it to my paypal address.

 

[BigE]

Any dual rail PS boards left? I'd like a pair for some F4 monoblocks -- will that work?

 

[xrk971]

Yes, I think there are a few left (circa 4-6) how many more do you need? It will indeed work for an F4.

 

[xrk971]

Paid. sorry, was travelling.

Thanks - it would be best if you cohange the PP address, but if not we can manage if you are unable to change.

 

[BigE]

Minimum for two monoblocks would be two? That's what I 'd like please.

Hi X,
Must the CRC resistor be a total of 200 mOhm or can a single 100 mOhm Caddock 960 be used? I have a bash of them in a tube waiting to be used.
Kevin

 

[BigE]

Paid!

 

[xrk971]

As long as the heat dissipated is less than the rating. Preferably half the rating to keep it cooler and run a longer life.
