Help with Electronics Repair, where to find the right fuse?
MajorHavoc:
I found myself in a similar spot a number of years ago. I had a small portable TV that went dead on me. After much digging, I found the culprit. A small Buss fuse buried between the main wiring bundle and the circuit board. The local electronics shop could get the fuse I needed for the low low price of $23.00 plus tax. I inquired about the same value fuse,standard size with pigtails and was delighted to find that the price was about $1.25 out the door. I soldered the pigtails to the old fuse and reinstalled in the set and it ran flawlessly for years until the picture tube ultimately gave out. Good luck.
Ed_McCarron:
This place gets me fuses by the 100's for about a third of the price I'd pay for the little 5 packs. I assume they sell smaller quantities.

I was able to order a pair of fuses online. In case others are interested I used Digi-key. Price seemed reasonable. I paid $3.00 shipped.
Sadly as some of you suspected the unit must have bigger problems than just a fuse. I suppose I should break out a meter and check both the PS and the fuses...
But it's probably Dead.

a faulty bridge rectifier will cause the fuse to blow. it's the first thing after the fuse. most susceptible to power surges.

I don't think they normally short though. I'd be looking at big filter caps nearby.
