If I can attach pics to my post, then im sure I can.
Ill get it posted a bit later.
But its like I said, more of a diagram or cartoon than an actual schematic.
There is also the build Manual.
The pcb looks to be double sided. Seems pretty easy to trace, but as you know, Im no electronics wiz.
The largest cap I see on the PS board is a 220uf. It seems its AFTER the B+ and choke.
I could be wrong, so ill post pics.
Regards!

DAK-
Sorry but its not working for me.
The post looks normal when I hit "preview post" with the pics attached, but when I hit "post message, it doesn't show up.
Perhaps I'm not a member long enough (6 days) :)
I ordered 20 new fuses, and a new rectifier tube.
I figured I should have plenty extra of these anyway lol.
If this doesn't do it, then ill have to send it out for sure.
I know ANK uses a builder for their kits when customers choose not to DIY, but I cannot recall who it was.
I think he calls himself "Digital Pete".
I had a couple of hurdles to cross during the build of this amp back in November,so between that and now this, perhaps I've wore out my welcome with Brian :(
I'll report back on how it goes.
Thanks for trying to help me out.
Regards!
Hello all.
I said I would report back with my attempted repairing of my ANK kit 1 300b set amp.
A few days ago, when I received my new fuses and my new 273b/5u4g rectifier tube in the mail, I installed a new fuse, installed the new rec. tube, and gave it a shot.
Once again, upon switching on the amp, the new rectifier tube would spark, and the fuse would blow. I replaced the fuse and re-tried two or three more times, with the same result.
With still not hearing back from Brian, I decided to try and reach out to "Digital Pete",
ANK's kit builder.
Well, I got lucky there,
as Pete took the time to walk me through some different voltage tests.
He came to the conclusion that I should try a 5u4gb, which apparently passes twice (approx.) the current of the other rectifier tubes I tried (including the 5u4g).
I was rained out from work today,
so I was able to confirm some final voltage measurements with Pete (which he described as "textbook"). I then tried one of my new 5u4gb tubes, which I received yesterday.
So far so good.
No spark in this new rectifier tube on start-up, and no blown fuses as of yet.
I have turned it on and off several times, and I also let it play for several hours today (getting nice and hot).
I sure hope this takes care of it.
Regards!

Late but as you seem interested and never got the reply I did find this manual on the net which I believe has schematics.
