Picked one of these up cheap but with no manual or chart. Does anyone have one they would be willing to share?

Hi Larry,
Just let me find the time to scan some tube chart and maybe a little part of the manual, I haven't a full manual but this tester is easy to use, the settings and schematic are almost identical to the Heath TC2 of wich this is a clone.
Ciao.

Hi all,
Now I have scanned all of my CTI TC.20 tube charts and 21 pages from the wiring manual, if anybody needs the data just let me know!

Ciao.

Greetings, Tubesaver (Max from Italy)!

I see you have manuals scanned for the CTI TC-20 tube tester! I have the charts for setting up the tubes on the tester, but I have no other manuals for it. Any possibility that I could get a copy from you?

In particular, I'm trying to find out what the bold letters vs. the normal-type letters mean, when putting the switches up or down.

In case you can't tell, I'm new to tube testing, so any help would be appreciated!

Grazie! (I think I spelled that right!)

Could you send me the charts and manuals? I would greatly appreciate it! I picked up the tube tester today. It came with no manual.

Reviving this old thread in hopes someone can forward me this data as well (markojerry at hotmail dot com), thanks in advance! In the meantime I'll look at the Heathkit TC-2 data.
I also have a CTI VT-20 VTVM coming, I'm guessing that may be a Heathkit clone as well?

Cheers,
Mark
