2stageEF high performance class AB power amp / 200W8R / 400W4R

Of course you are right. For me it is a (very little) disaster because I have tons of 22000µF/80V with 5 pin layout ...

Ah, now it's getting clearer! I've been wondering why you've provided this 5 pin footprint at all, 'cause these parts are the most expensiest of all, at least here in Germany :confused:.

Another question: Did you do any layouts with a single diode bridge for both rails? As stated yet, I don't see any advantages in two bridges.

Best regards!

All my previous power supply designs are single diode bridge - nothing wrong doing so. Just wanted to bring it to the max.
According to recommendations of e.g. Bob Cordell and Nelson Pass I decided to develop a dual diode bridge power supply just 4 fun.

Have Fun, Toni

Attached the corrected version. Now the 5pin lytic layout should be OK. Have a look on it and please report any errors ... :)

Note: Gerbers are free to use only for non commercial DIY projects.

Changes from v4.1 to 4.2:

  • 5pin lytic footprint should be now OK

A very, very simple front panel switch PCB for diyAudio projects. Toni's Main Control Unit can be set up for a momentary action switch for power-on. This PCB has a little 6x6mm momentary, normally-open, tactile switch and LED for power on/indication. (It could easily be revised to add a standby LED also which Toni's MCU provides for.) The actuator is up to the user. Perhaps a 'button' from aluminium rod, brushed to match the front panel with a simple o-ring to hold it in place a la my builds.

Board is 20mm x 44mm and the LED is 10mm down from centre of switch. I'm going to do a panel run of these and so will have a lot of spares if anyone is interested.

... working samples!

First picture:

  • High voltage, high power version for SA2014 see pcb on left side (max. +/-80V)
  • Lower voltage version for SA2015 and SA2016 see pcb right side (max +/-50V)

Ok I think this matches. Perhaps you can double check. (It is a bit confusing because the pin orientation of the symbol in Eagle is different from the package orientation.) This should also allow a 4-pin Molex or similar as with the MCU board and a 2-pin directly under it - connectors mounted with 'clip' to the left, pins to the right. I wanted to make sure it works okay with a right-angled 6-pin header (0.254 pitch) for those situations where space is at a premium.
