That's what I used. Long time ago. :) In fact, I have it in my hand. I was just going through some old boxes. Isn't that the craziest!

Here is what Nak recommends: DM-10

Keep your tapes AWAY! lol number one step. you basically just make contact w/ any metal parts the wand can reach, i've never had to get more into than that. i think the standard recommendation is to de-mag about every 15min of play/rec time. i usually just do it at the start/finish of a session if i'm using tape.

also... as you degauss, start with small circular motions over the head, widening those circles as you pull out and back.

If you have MR2's, the doors are removable and slide off, making access to the heads a bit easier.

fwiw
