the or/yel are not twisted on their route to the rectifier.
I wonder if the red/blk are similarly untwisted?

oiphy

now I see that you resize them nicely , so you can directly upload them here

reply-manage attachments etc , same as with first pic you attached here

you can use DB for larger ones

edit : ups - just first one is adequate in size for attaching here

I think, 50 VDC you got from V+ and V-? not from V+ and Gnd or V- and Gnd,..Do you?

first - search for "bulb tester" ( AndrewT is strong proponnt of that tool , with reason) ;

make one

connect amp via BT (say that 40-60W is good for start)

disconnect amp pcbs from PSU and test just PSU

from pics I see that you connected Graetzs as needed - check polarity 3 times before powering up!

power up and measure voltage on each output

BT will lit brightly and dim after sec-2 if everything is OK

if BT is bright for prolonged time , something is wrong

measure voltage between each + and gnd - you can expect DC voltage in range Vac x 1.41

measure voltage between each - and gnd - same voltage ( opposite polarity , off course)

example - for 18Vac secondaries , you can expect 18x1,41~25Vdc

when you are done with that , report here

but first !! write what wire colors are written on xformer - we need to check did you connected secondaries as needed
