The particular stuff I used is no longer available but it was very good. Some variety of Multicore glop.   I notice that the new replacements only have a 6 or 12 month shelf life and are quite costly in small (syringe) quantities.   All my stock of solder is now old (15 years +) and the flux is ineffective. Looks like I'll have to find a syringe of some goo for my next job.   -- Blow my nose to email me

I recommend the MG stuff because it seems to be stable, whereas the Kester stuff crystallizes out after a few years.   Cheers   Phil Hobbs   -- Dr Philip C D Hobbs Principal Consultant ElectroOptical Innovations LLC / Hobbs ElectroOptics Optics, Electro-optics, Photonics, Analog Electronics Briarcliff Manor NY 10510   http://electrooptical.net https://hobbs-eo.com

George51@nospam.com: Nov 01 01:43AM -0500 Back in the 1960s I was given several heavy tube amplifier chassis. All of them worked after replacing a few tubes. After all these years, I still have them. They were very well made, The transformers were not shaped like most, but were in square cans with rounded corners.   Another unusual thing, was the three part filter capacitors were plug in, with an octal base (same as an octal tube). Back then, I had a little hum so I found a store that had identical replacements.   The tubes were all octal based. Four 6L6 outputs, Two 5U4 recifiers, and at least 4 more octal tubes. I believe at least one was a 6SN7 (something like that). I dont have them handy to look at right now....   Anyhow, they had awesome sound and were loud. The audio output transformers were huge.   However, there was no brand name or identification of any sort on them.   50 years later I am still trying to ID them...   I think they were from jukeboxes. But that is just a guess....   I have tried to google different words but not found any matching pictures. I did note that the Rock-Ola chassis all seem to have those square transformers though. My guess is that they were made in the late 1940s or 1950s.   Does anyone know of any website that has photos of antique jukebox chassis, or another means to ID them?

Eremita Analogico <LEDITApaolo.carrer@DALNASOlibero.it>: Nov 01 09:23AM +0100 Hi, The output transformers seem to be Acrosound, very good transformers. Try looking for Williamson amplifiers schemes, depending on the valves used there could be a similar scheme. Do you sell one of these chassis? Also without tubes.

Most have square boxed transformers, 6L6G and other octal tubes and electro dynamic speakers.   But none had plug in electros on octal sockets       .... Phil

"pfjw@aol.com" <peterwieck33@gmail.com>: Nov 01 04:10AM -0700 Back in the day, RCA made theater amplifiers as you describe, up to and including the potted transformers. These things were massive and usually rack-mounted.   The logos were enameled medallions, so if they were removed, you would have no other indication of the maker.   https://thumbs.worthpoint.com/zoom/images3/1/0410/17/vintage-rca-type-mi-4288-mono-tube_1_b74613f650ed1caef9dc8c6b2b59c8f9.jpg   When theaters started replacing tube systems with solid-state and multi-channel systems, many thousands of these amps got trashed, and a vanishing few found their way into other hands.   Peter Wieck Melrose Park, PA

Since you described them as physically large, I think a theater amplifier would make sense. The fact that the electros were easily replaceable seem to indicate that they are specifically built to be serviced quickly and on-site, which again favors both jukebox or theater amp.   We have a resident jukebox expert here (John Roberson?) who might be able to add some thoughts.   In the meantime, can you post pictures of these amps to a hosting site?

Since LEDs don't put out any significant light until they reach close to their run voltage, maybe his controller just ramps up the string slower than the one in my 8 foot tubes.   >The fact that all his examples do the same tells me it's just the way it's designed and not a failure.   >And once again, he DISCONNECTED the ballast and wired them directly. I just replaced some incandescent bulbs with LED bulbs and they have a delay like the OP describes. The new LED bulbs are the dimmable type. I wondered if the delay is coming from a cap being charged through a resistor. They also have an off delay similar to an incandescent. Not exactly the same but they do dim until almost completey off and then abruptly turn off all the way. Eric

genecarter2@juno.com: Oct 31 10:22AM -0700 I was playing a tape and it got jammed. When I pulled it out, a part came loose and now I can't find where it goes. Can anyone help with this part location ? It's in tact, not broken.
