I'm getting a Sencore CR70

[Jon A.]

I suppose it depends on one's preferred level of simplicity. Here's a photo of the inside of my parts unit.

This is as complex as I care to see. I wouldn't want to see inside a CR7000.

IMHO service gear is better to have in beat up, but working shape. I take my CRT tester to most swap meets and places where I anticipate finding vintage TVs...It gets beat to heck riding in the car and being dragged everywhere, and I'm glad it did not come to me prefect as I don't ever feel bad adding wear.

Perfect gear is like finding a good LP still in the shrink wrap...You end up torn on whether to enjoy it as it was meant to be or keep it perfect.

I cleaned the CR70 as much as I could, and it actually cleaned up well. I went to Lowe's to try to find plastic feet for the bottom, and nobody had any idea what I was talking about. I tested it out, and aside from the fact that you have to change the settings for each color, I like it a lot.

Look in the closet or cabinet hardware area.
I bought, what they referred to as sliding closet door bumpers at a hardware store. They looked like rubber feet, but they were white. The screws, they included were wood screws. I used 6/32's.
BTW, my CR70 was missing a foot as well. I looked through my hardware and found one that was close in size.

Man, this is an epidemic! My good one was missing a foot and I think my parts unit was as well. Its case was in rough shape; bashed in on top, rusty hardware. I trashed it some time ago, keeping some parts for the good one.

Neither Lowe's nor Menards (the latter usually more likely) had "plastic feet".
No idea what they were.

But Menards had "furniture slides", a very large display. Amongst them
were plastic feet of all descriptions, also a large selection.

What Lowe's does have is a large selection of misc hardware stuff that
we need, especially for boatanchors. Cotter pins, standoffs, those clips that
hold shafts in place, nice 4x4 inch sheets of metal, etc. They are in the drawers
under the bolts and nuts, look in "automotive" drawers there too. (Edit: By "there" I mean
under the bolts and nuts. If you need odd hardware, try there first. Don't believe
the drawer labels, check everything at at least once to get an idea.)

Lookin' good. How many feet are missing?

Amen to that. Better to use the heck out of them than turn them into shelf queens. As long as mine isn't rusty and doesn't have massive case damage it's fine by my standards. When mine got to me, the foam rubber holding the socket adapters had disintegrated completely and made a huge sticky mess. Once cleaned up it was fine.

Three feet are missing, and the fourth is not far behind. The foam in mine is definitely starting to fall apart. I wonder if you can buy that foam stuff anywhere?

[Jon A.]

I'm sure foam rubber is readily available, maybe you could just liberate some from a trash-bound couch cushion, it'll just have to be cut to shape. The foam from my parts unit is okay but I'll have to cut new stuff eventually.

It's kind of like what happened to a lot of 8-track tapes; most foam pressure pads rotted and fell apart whereas some are still as good as new. Those could be made of Polyurethane foam, that's what's in my chair anyway and it's getting along in years and holding up fine.

I just gave the CR70 a real life test by opening up a 2006 Durabrand TV that was dumped upon me, and unfortunately, the A34KPUO2XX was not in the book. I looked at the universal adapter, and saw some numbers that I think might correspond to the pins. I don't have a manual, and the abbreviated instructions don't address the universal adapter.

That TV ought to be good for a satisfying pop when dropped from a considerable height.

I think you'll do a-ok with the CR70. It may not have three gauges but it's not like speed matters anymore. Test enough delta tubes and and you'll only have to look at the book briefly if at all in most cases. I'd say your CR70 was a fairly decent bargain, many sellers really try to soak for them.

By the way, try an arts and crafts supply store for the foam.

Just found the CR70 manual online. Printed out all 55 pages, hole punched them, and put them into a 3 ring binder. Now I have some nice reading material for school.

Lots of feet on Amazon:

I got my CR-70 today. If it is working correctly, only one out all my non-electrostatic
guns is actually good: the blue gun of my 15GP22 tests perfect. Its green gun
is a bit lacking in cutoff but emission is fine. My 10BP4 and 12LP4 both test
bad in cutoff and the 12LP4 is also a bit poor in emission. The red gun of the
15GP22 is abysmal in cutoff but about 3/4 of the way to good in emission.
This proves that the tube is indeed bad bad bad.

I'm surprised that the 12LP4 sold to me by the ETF tests poor to bad.
I tested both 5BP4s I have that are not in a TV. I don't know
what the cutoff is supposed to be, so I estimated it at 8 volts from the
spec that the "visual" cutoff should be 1 to 3% of the G2 voltage
(set at 415 v) . This proved roughly correct for both tubes,
which both tested borderline emission, though the ratio was
what I expected from use in my TT-5.
