    Those are some wild tranny's! you have my highest respect! I tried that job before. I worked at a chevy dealer in the early 80's, (700r4 comes to mind??) I could never get transmissions to work right! I could trace Electrical shorts etc in a cadillac, but never transmissions!!

    a custom burn in rack
    a couple more soldering irons
    2 Mil Bridge Capacitance-Inductance-Resistance Meters
    1 Heathkit signal tracer

    old fender 2 x 12 cab
    mini marshall battery amp
    hand built specialized test gear
    more special purpose parts
    various amp stands (concrete filled tranny boxes, 2 x 6 x 12s with bases,
    input jack jig

    Hey, would anyone be willing to purchase simple how to
    videos for tube amplifers? All the production will be done
    by my kids and all proceeds would go to my school program.

    I'm going to run a high school career and technology (vocational education)
    program and want to get the kids into doing some real production
    and credits.

    Anyone interested in a Technical Advisory screen credit etc?
    It is for the kids!

    I'm open to ideas.

    You guys should post pics of your workspaces! There are some out here who are total shop geeks and like to see that stuff.

    Amp nerd, what are you using the vacuum pump for? clamping?

    Lost wax casting.

    Saul, beautiful work on your Axes!

    My bench is a mess. I'd never pass
    a safety inspection.

    It works for me though. :dude

    Oh I have a file somewhere of my "early" bench.
    You can click on different things and it IDs it.

    Thanks for the link V846.

    Mine is a cross between:

    Dan Petersen
    and
    Darryl Boyd

    HOWEVER

    I keep things a tad more separated in the work areas

    AND

    Keep only electronics stuff on the bench then each in their
    own areas...hand tools on spot, solder another, irons another
    junk pile off to the side : )
    Related power tools in the garage (drill press, bench grinder, etc)
    a chemical area etc.

    AVO Model 7 & Model 9 analog long-scale multimeters (50s/60s)
    2 x cheap modern digital multimeters
    Tube signal generator (60s)
    Tube single-trace scope (60s)
    3A Variac (60s) - 240V mains over here, so 3A is plenty
    Own-made 400W resistive dummy load
    Marshall Powerbrake
    15W, 25W & 50W soldering irons (plus the gas cooker in the kitchen when my wife isn't looking ;))
    Two power drills (one variable-speed) and a rechargeable drill/screwdriver
    Tap and die set
    Dremel
    Large & (very) small hand drills
    A huge number of screwdrivers, pliers, cutters, files, spanners, hammers, solder sucker and other hand tools etc

    That's probably about it. You really don't need anything very sophisticated to work on tube guitar amps - they're very simple things really. The only really high-quality things out of that lot are the AVOs, and they're of the right vintage to match some of the amps :). The only thing I really need a better one of is a scope, but it isn't a priority.

    I've also come across quite a few repair techs with all the fancy accurate modern equipment you can think of, who still couldn't make an amp reliable for a working musician or sound right.

    Thanks,Im a "fixer" by nature,however I kind of hate cars now.lol! Im thankful they pay the mortgage but thats about it!Familiarity breeds contempt is the old saying?. Ive been working on trannies since I was 18. I'll be 46 on Saturday.I only wish I had the knowledge to work on tube amplifiers instead of cars. Now that would be cool!

    Hey-that's no fair! You can actually see the TOP of your bench! Mine has so many projects and repairs(junk) that you can't see the top. Luckily, the drill presses and other stuff are on other benches. THe top has two different vices on it-one soft face, one hard. I really need to clean up. Maybe Mike's nice clean top will give me some inspiration. Also luckily, my resistor cabinets and parts cabinets are under the bench so at least they are out of the way.

    I like Bill Meacham's "bench tester!" :)

    My simple setup is two small tables with scope, signal genrator, cap tester, VTVM and an older Fluke 23 plus a side rack of tools.

    Yeah, as you probably know by now...I use my ears more than
    most of the gear I've got.

    But when things start getting wierd...it is always nice to have
    some test gear to help out. There is nothing quite like some of
    the older gear...kinda like older amps.

    Can we say ears?


    :RoCkIn

    EDIT: Oh I'm NOT alone. I thought it was just me that had "projects" all over the place.
    Thanks y'all, I feel much better now.

    I would purchase a video or two, to help out. That is a great idea for a fund raiser. This is close to my heart.. My father taught Electronics at a votech after he retired from the military ( 1969). in about 1986-88 or so, He helped rewrite the text books for votechs. I dont know if they are still being used or not, but he put in the time! Most students went on to a career in electronics. It's great to have good teacher :AOK.

    I would be happy to purchase. Let us know!
