Thank, it's still under construction.....and it seems it will be for quite a while, it takes a lot more work than I though it would 🙄

Magura,
My suspicion is on very high secondary voltage. The DMM needs new batteries and the reading cannot be trusted, which I will fix this evening. The high voltage probably destroyed the electrolytic caps (C2, C15, C16) which resulted in high currents through the resistors which blew it. Although there was no smoke, I think, I might as well get ready to order more caps.

Hi Dinesh.
Did you by accident connect the secondaries, wrong? It has happened before. Check the secondaries with your DMM (AC) to see if they are connected as they should be. It sounds like you could have two "hots" connected to one side of the psu.

The key word here is as far as I'm concerned "FUSES" as in NO fuses.
Get yourself a handful of fuses, and try again after measuring the secondary voltage, BEFORE connecting the trafo.

I had the tech drawing from Plitron, it is a little unlikely. But yes, I agree, I will check again tonight and make sure I did not mess it up.
No Fuses I meant, the fuses on the board after the bridge and CRC. What I was trying to do is to make sure I was getting right voltages from trafo and bridge. Everythingelse, Shunty and Pumpy were not yet in the circuit. I have a fuse on the primary, which also blew out. 😱Magura said:

@dviswa :
if you are using fusible resistors , sometimes they are more prone to burning than usual stuff ;
anyway - use 0W5 either carbon or MF with value of 2E2
I wrote that in Cook Book , in addendum ;
I have no these problems , because I use just 1mF caps in my Shunty , but sp300B was first who tell me for that problem ;
that's why I added that note .
regarding fuse in primary ......... 😕
be sure that secs are polarized/phased regularly , and that fuse isn't too dreky for xformer size.

Please do not let me describe the sound. It sounds rally good.

ZM,
Sorry I did not see it. I will fix the values when I reorder.
Good to know that I am not the only one.Zen Mod said:

I verfied the connections and measured again. I am getting open loop 54-0-54 on the secondaries 😡 . Surely, way too high. I have requested the manufacturer to fix this, Let's see what comes of it. After that I have to order and replace all teh lytic caps.😱
Also noticed that my home supply is around 125V instead of the rated 110V 🙄
