Subject: Re: TRS-80 Model 12 crt substitution
The old method for this is 'tighten until the CRT implodes,
then back off
quarter of a turn' :-). [Note : If you don't realise this is
a joke, then
you shouldn't be attempting a CRT replacement, OK!!!]
Hehe! I've only ever decompressed one tube by trying to straighten a couple
of the pins on the back. The sound of the air rushing in was quite
disheartening :)
isn't in the M4, so there probably isn't in
the M12 either --
the CRT can
hold a charge for a lot longer than 'overnight'.
Ah, I didn't know that - I thought they discharged naturally.....
and it may cause you to drop the CRT. I alwayse
discharge a
CRT with my
EHT probe before handling it.
I should really get hold of an EHT probe 'cos it would save a lot of
waiting!
Cheers
