    Its a JTM45 chassis, I had made, with fewer pot and tube holes, for this bastardized Supro Thunderbolt 6420 circuit. I hacked up a layout on a fiberglass turret board, got some standoffs in the...

    Hi Chuck! Don't know. I have the board built, parts soldered in and some wiring hooked to that, but not bolted into the standoffs. The last task before putting stuff on the chassis is to get the...

    Cool, thanks Enzo! That would save a lot of hacking and dremeling, none of which Im particularly good at. I had started a discussion about the orientation of the cores, and got lost in the...

    Hi Loud, nope, all the wires come out on the bottom of one bell. So if I take that bell off, the bundle would fall into the inside of the chassis.

    Converting a stand up PT to a laydown

    Hi All.
    Not being able to leave well enough alone, Im talking myself out of taking the end bells off a standup PT I bought, having my friend dremel the feet off, and making it into a laydown....
  7. new old computer needed -- anyone have opinions on old dell 7810?

    My old Dell Dimension is sometlike like 2005 is showing its age. Can't install anything on it anymore, and its too slow to run newer OS.

    The old E510 had a fan problem years ago, and I think...

    Not too far an aside, but how do you all do voltage measurements on an PT that isn't hooked up yet, assuming you know what the primaries are? I mean, do you clamp the transformer down to the bench,...

    Yeah, I like the Belton 8 pins. Solid. But their 9 pin sockets at least the ones Ive gotten, seem a lot more flimsy.

    Thanks again everyone. As far as I can tell, these really are brand new, just have not been stored in a perfect environment. I bet a warehouse with less than optimal humidity. I will grab a ...

    Thanks! I have some deoxit but I think it has some lubricant in it, its for pots. Will look for the non lube stuff and buy a can.

    Thanks everyone. Yeah, remember that the amps distortion was not good tube distortion. Thought the clean tones were ok. But, 40+ year memories aren't very accurate. :) Don't see them very often,...

    Found a 30-20-20-20 525v can cap on antique electronic supply a little below 40 bucks. Someone on one of the MEF threads said something about the chokes going bad. Triode has one for 35 bucks. If...

    Thanks, Loud. That was the reason for looking at this one, price. Its 750 with 2 x 10 cabinet. Most of the Reverb listings Ive seen were a lot higher. Ad says "not into negotiation", but .. meh,...

    Thanks Enzo, maybe just damp storage damage? If it plays well, and runs for half hour or so without emitting smoke, tending to want to buy it. Its couple of hours drive, so I have to arrange the...
  17. Opinions: 1968 or so Sunn Sceptre with cabinet for sale

    Hi All!
    Back in the day, I had a Sunn Sceptre head, loved the tone, sat in Dads attic until they moved and sadly it got tossed. I look on craigslist and reverb from time to time, they don't...

    cleaning NOS tube socket contacts

    Hi All,
    I have a handful of really nice cinch NOS tube sockets for a work in progress. Not a scratch, and no hint of solder so Im sure they're "new" nos rather than removed from service. ...

    Of course, a lot of my problems could be that I don't know enough about the parts Im looking for. :)

    I believe you on that Helmholtz. In the 25 years Ive lived around the North east, Ive seen local shop after local shop close up and go out of business. When we moved here in the mid 1990's, the...

    At a previous company, once in a while we'd get a new laser from the German factory, plug it in, turn it on, and get a nice "BAMM". They usually worked just fine, but we swore they put a cap in...

    Thanks again Leo. I haven't had many amps, maybe dozen or so max, and played through a handful of others, mostly junky amps in friends basements. There are some guitar tones I haven't heard from...

    Leo, my friend Steve's dad taught him the fine art of TV repair. This is late 60's through the 70's, when there were still many tube TV's in service. He has a standard joke, they have 2 x 100 foot...
