Having lost my one good tube repair guy a few years ago, I'm still looking for a competent, affordable repair guy anywhere, let's say, from Philly down to North Carolina. I'm in SE Virginia and at thi .......

I have a Decware ZMC1 MC step-up transformer, which is passive but is adjustable by a knob on the front. If I'm going to use it with my Pro-ject phono pre (which also has continuously adjustable loadi .......

Posted by strhd07 on 2018-08-06, 10:32:15 (172.164.15.39)
I'm pretty diligent about cleaning both pins and sockets, with socket brushes, rubbing alcohol, and then some Deoxit for both sockets and pins. Whenever I might swap tubes, I always give a new swab wi .......

I have a couple pairs of OS tubes, from the '40s and maybe even from the '30s. On start-up, one of them makes scratchy noises for several minutes and then behaves and is quiet for the rest of the time .......

I found out, after I'd bought and had it refurbed and calibrated some years ago, that the 536 doesn't have settings for some tubes I use. It's been a while since I last looked, but I checked again and .......

Posted by strhd07 on 2015-11-25, 15:08:59 (172.164.3.234)
Thanks to all for the replies. Best I can tell, there are at least two things going on here (maybe more): one legit, one not so much. First, it seems the output trannies for some amps are more narrowl .......

Posted by strhd07 on 2015-11-24, 17:47:52 (172.164.128.197)
I'm sure the dealer isn't saying this to sell a relatively inexpensive extra set of tubes to me (the amp comes with a tested set), so that's why I'm puzzled the warranty is being made dependent on usi .......

I'm looking at getting a used, self-biasing E34L amp from the dealer/distributor, and he says that only the exact types and brands of power tubes and input tubes that come with the amp should be used. .......

Posted by strhd07 on 2015-01-22, 03:21:27 (172.164.53.179)
Appreciate the help, but for those who haven't used four-pin tubes like the 45, 2A3, and 300B, the sockets don't have a center hole that would accept a guide pin, which is why, as Garg0yle says, it's .......

Just got a 45, standard ST shape and "45" stenciled clearly on glass, and it tests fine as a 45. But it has a brown base (which I've never seen before on a 45) with no markings, and what's hinky is th .......

The fuse in my Korneff 45 is a 1A 250V, but does anyone know whether it's a slow- or a fast-blow fuse? And is there some rule that tells you whether an amp uses a fast- or a slow-blow fuse? Thanks, Ma .......

Anyone know what tube tester will handle the 6C33C? I'm in SE Virginia and hoping there's someone within reach who has a tester so that I could bring my tubes over and see that they're all healthy. Al .......
