So are you going to share pics of your diesel powered tape deck? ;^)>

In retrospect I think that stuff from Fry's might be pretty close, maybe it was 99.4%  rather than 94%. Anyway, I doubt it makes a huge difference. It's just supposed to help dissolve the adhesive crud, not increase the horsepower. Everclear, being a dual purpose solvent, might actually make the music sound the best.

If we have a really gnarly deck come in we skip alcohol and go right to naptha for cleaning everything in the tape path but the pinch rollers. Just gotta make sure you don't strip the grease out of any ball bearings.

Hey Bob,

I was a little confused by your statement that you plan to have the 32-2b rewired for use with an outboard amp (Eros etc) giving one of the reasons that it's already IEC ready.
If you do the direct wiring from the heads of that machine, it will bypass the IEC circuit (unless you plan to have it switchable from direct out and internal electronics).

On another note, I never had a hangover until the day that I decide to relieve my roommate of some of his Everclear stash. That was my only exposure to that volatile potion and I've never had another hangover since.
Scary stuff!

As Steve attests the head rewire will creat a need for a tape preamp that's switchable - NAB or IEC(CCIR). You can use the 42 for this purpose and keep the dual EQ 32 for mobile tape playing when you come over to play some tapes.

As for choices there are a few tape preamps out there. Doc sells 2 and has instructions on modding a third. For fairness there is also: http://www.dehavillandhifi.com/222_Tape_Preamp.htm and Charles (Stellavox) King Cello tape preamp http://web.me.com/reeltapes/Home_of_Reeltapes/King_Cello_Stellavox_Page.html.

Re: Tascam 42B tape path cleaning care

Hello all,

I've headed your advice to stay far away from rubbing alcohol, but was able to pick up some alcohol that is 91%. I hope that will do the trick regarding cleaning the tape heads. I've also picked up some formula  409 which I plan to clean the pinch rollers. The tape deck seems to be in great condition and apparently well taken care of.

Actually, I was not aware of the fact that my 32-2B Tascam does not require any additional wiring other than the Cardas wiring directly from the playback heads. Is that right? On the other hand my 42B must be modified from it's present state of NAB to IEC.

Saving up to become a bonafied member of Tape Project is for me a long and drawn out affair. Had I not let me new wife talk me into buying a house a few months ago I would have been set. I tried to convince her to move into a 900 square foot house instead of this gargantuan 2800 square foot place. Just goes to show how selfish some women are. Well, what can I say, but, I've just got to keep plugging away:). I can't wait to be able to get my hands on a few of those great Tape Project tapes.

Hello DocB

I am finally able to get a small photo on our forum here of my Tascam 42B deck. I think I could have uploaded a little larger version, but, I did not want to chance it. In the past I've tried a number of times but was unsuccessful. Today, victory.
