dear zen mod
think I found the problem. I use this power supply
and there are to outputs from my torrodial +25 -25 and I connected them both..1 on the left side and one on the right side. removed one of them ten volt is 25....
so guess i need to go for single rail ??
so ...what do you think?
2. think i blow up something?? no smoke or exessive heat...

I think that this is pic of article on which FW is used without permission
further - my crystal ball is muddy these days , so I can't imagine how you populate and connected that bare pcb from pic
hold your horses ; you're playing with some money , serious amount of energy and - most important - mains voltage ;
so - lack of knowledge and experience you must compensate with careful planning and thinking ;
I said - post pictures of your work , so we can see and comment
search forum for bulb tester ; convenient tool for novices

pics tomorrow morning
and thank you for helping me out.
already scrapped a china set from this guy do to copyrighs, so i toght i've would at least save thes boards since they are already populated with kendeil and what not.. wallet will probly die if i have to scrap them 2...
pics comming soon. thanks

power supply
hello.
input torrodial 230v blue brown. sec1 black red 18v. sec2 orange red 18v
So after meassurement this is what i have:
output rectifier 1: 16,6 vdc
output rectifier 2: 16,7 vdc
so question is : how do i connect this ? se 3 post earlier for cond bank that i use. ( have 2 of them) but really wanted to use only one.
pics of amp to come in a few hours
ps. Zen Mod: the letters of FW onboard will immediatly be removed. I bought this item before I knew of this "copyright" violation. So when I was told I made a donation to pay for my sins

I'm waiting for pics
DC voltage is too low ; is it measured with just diode bridges , without caps mounted on-board ?
yes probes directly to diodebridge without caps con.
of to town to buy new camera.... old one is broken apperantly
That's great idea,
Seem your DC voltage to low like ZM said,
with input bridge 18 V (AC), output must approximately 25 VDC from (18 x 1.41).

so here some pics. if I could only get them uploaded!!!!! seems there is a problem with uploading now...
when only 1sec is con. I get 25vdc on the powerboard. problem is when I con. the 2sec from torrodial then I get 50v. so.... what to do? think I read somwhere a while ago that there should be a way to con 2 secondaries... thank you all for any help.

I don't have FB account ....... and I really don't need it
So...you tried to follow the link and no pics?
know where i can upload?
thank you for your patience.
trying again

for now they'r not twisted. but the problem is getting it up and running, or should I say them (have 2 monoblocks)
for now Im getting 50 vdc to psu when 2 sec is connected... look at pics.. see I disconnected one sec. and then I have 25v soooooooo whats wrong ??

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
