Single Ended Triodes (SETs), the ultimate tube lovers dream.

RE:Just hit the "browse" button nt

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!
