Schematic Links, Tube retail links, local tube testers

Southern NJ, Eico 667 with a 615 adapter. The 615 gives me the "big pin" pre-octal types. I also have a collection of Riders manuals from volume 1 - volume 17 and an incomplete Sams from folder 1 through folder 390. There are some gaps though.

Gadget tested a couple of dozen tubes for me this past weekend for which I want to thank him. Weeded out a couple of bad tubes. Thanks, again.
 
I am now rigged with a Hickok 6000 and 6000A.

I've gone through the calibration steps and verified operation.

I also have an Eico 666 and HK TC-2

FWIW, I am rigged with Variacs also, so if you find something that needs to be resurrected, I have that too.
 
Camden County, South Jersey. Close to Philly. TV-7D/U it's a Dan Nelson calibrated unit. Also have EICO 628 and 667.
Variacs and scopes here, too. HP 331A Distortion Analyzer as well.
 
I've been using a Transcendent Sound tube tester that I built from a kit about ten years ago. It's been very reliable and versatile.

Over the last twenty years I've purchased tubes from most of the vendors listed in this thread. I've had good experiences with one exception: Upscale Audio. Terrible service. They claim superior testing but much of what I've received from them doesn't indicate that. I think their major strength is marketing. There are many other good tube vendors out there. No need to buy from Upscale Audio.

Edmonton, AB, Canada. TV-7C/U & Eico 667 tube testers.
Stark 'scope, Military signal gen, Heathkit distortion meter, Heathkit audio vtvm. Simpson 260, etc etc. B&K sweep frequency generator (FM alignment), bunch of other junk.

Can repair the following:

Vacuum tube amplifiers, receivers, etc.
Discrete solid state amplifiers
Vacuum tube televisions & radios (pre-1970 or so)
Record players and turntables of all descriptions
Speaker crossovers
Vintage tube Guitar amplifiers

Willing to help other hobbyists, especially if it suits my interests . Not very interested in late model equipment with circuit boards, but contact me if you've exhausted all other resources, I can probably get it going.

Check the top of this page, http://www.vintage-radio.info/heathkit/index.htm, maybe yours is in there i could not find just thirty six - Good Luck
 
Hickok TV7A-U tube tester and a 5A variac, plus a scope, signal generator, LCR meter and such. Have done occasional tube amp and preamp builds, mods and restorations for various AK members over the years as well.

I also have an Eico 625 tester, but it's not been restored or re- calibrated.

Located in Marietta GA.

Regards,
Gordon.
