Hi everyone.

I'm a proud owner of a Beomaster 3400, which blew the primary fuse a few days ago. I really would prefer to fix it myself (or try my very best) than to send it to the butchers on the official B&O repair service here in Portugal. The last time I sent it there it came back missing a few parts, namely the metal 'rods' that held the cover up when opened and the aluminum spacers thay lay between the wooden frame and the panel itself, plus a misplaced linear pot and they failed to tell me they didn't fix the tuning dial string thing-y which had broken off, although I requested it...

Long story short: it's blowing the primary fuse and if it's a simple repair I'd very much rather do it myself. Does anyone have a clue on where to look?

Although probably unrelated, the D8 rectifier has failed in the past. Testing the four 1N4007 diodes the official B&O repair service here in Portugal soldered together showed one of them was gone and I replaced the whole thing with a W01M.

Also, somewhere along the way someone put a 1A (fast) fuse between the secondary and the D8, and TR8 has also been messed with. Does anyone have the original specs of D8 and TR8?

All the best
