[chbot] Chchrobotics Digest, Vol 155, Issue 20

[Ivo Gorny]

Hi Chris,


I don't know if this reaches you - i have trouble with the list for some
reason - my yahoo account does not get the trails - at least not all of
them, and this work account runs on Google, and for some reason I
cannot edit the "Re:[chbot]...". Please can someone reply to let me know
this reaches the list.


Anyways, regarding Reel to Reel tapes:

Do you want to use one or display one?

If just for display: look for something cool looking, clean it, if the
reels rotate, even better, that's it.

If you want to use it:

- try to get at least 2 similar ones to get spares

- the heads might be worn

- the motors might be worn

- the belts will be gone or worn (!)

- the pinch roller may be hard as a rock

- the whole mechanics will need an overhaul

- depending on the age of the electronics, your electrolytic capacitors
will be gone and/or leaked, meaning, you will have to replace them. Yes, no
kidding.

- and, of course, everything needs to be proper adjusted (head azimuth,
speed,... you get the picture)


I have a very good friend in Germany doing this with professional
reel-to-reel tape recorders like Revox, he is even asked for his service
from museums and collectors outside Germany. He surely will be happy to
help with advice.

I will do this later for my old Philips recorders, but right now the house
and renovations are more important :-(


Regarding tapes: I haven not seen/heard of mold, but what happens, is, that
over time the binder (binding together the ferric particles and the
polyester tape) is disintegrating and becoming a smeary mess. You can bake
tapes, but that is - eh laborious and risky. So, if you want to use this
machine, get new tapes, they are still made and sold, but not cheap.


Hope that helps a bit.


Ivo
