I'd like two recommendations for equipment (brand names, what
do you have, prices, etc.) now that I have moved into the world
of three head recorders:
A wand - type tape head demagnatizer
(I have the TDK looks-like-a-cassette demag, which is fine for the
two head machines, but it should not be used in a three head machine)
Tape head cleaning fluid that can be used for cleaning the heads
and rollers/capstans without drying out or degrading the rubber
parts.
Thanks for your help!

The cassette-demagnetizers are fine for 3-head machines which have the play & record heads in a single housing. Aren't they?

I've used this on my Nak for a couple of years now, and I can't see spending more $ than this. > >Tape head cleaning fluid that can be used for cleaning the heads >and rollers/capstans without drying out or degrading the rubber >parts. > Most authorities recommend Isopropyl alcohol, at least 70% (available in your local grocery store) but better is 90%, from your local drugstore. The only this to watch for is whether or not the brand you buy leaves a residue when dry; dab some on a piece of rubber and see. The stuff is really cheap, and works well. If you want a commercial product, use Discwasher fluid. >Thanks for your help! > >Ihor Welcome! > 1847 West Main Road * Portsmouth, RI 02871-1087 * (401) 847-8000 ext. 5684 >0 1 2 3 4 5 6 7 8 9 !#$%^&*()_-+={[ }]~`:;"'|\<,>.?/ 9 8 7 6 5 4 3 2 1 0

No! No! No! Whatever you do, never use less than 99%! Anything less has significant water content to cause long-term oxidation of the metal components in the mechanism (i.e. heads, capistan(s)) and thus wouldn't be a terribly good idea. Anyway, every drug store has the stuff and at just over $1 for 16 fl. oz., it really isn't out of the price range for most audiophiles. I've heard of people using liquid freon, but can't see any distinct advantages to this... >The only this to watch for is whether or not the brand you buy leaves a >residue when dry; dab some on a piece of rubber and see.

The stuff is >really cheap, and works well. If you want a commercial product, use >Discwasher fluid. Alcohol is okay for the heads, but KEEP IT OFF THE RUBBER. The alcohol will make the rubber old before it's time, drying it, and causing it to harden and loose traction. As recommended don't use the 70% alcohol. Get the "pure stuff" at your drugstore - typically used for cleaning syringes, etc. And if you want commercial stuff - don't go with the Discwasher fluid. Get some professional cleaners - I have had excellent results with the chemicals from Miller-Stephenson. They even make a head cleaner for pro-video recorders that can be sprayed on while the unit is playing/recording.
