Once we get the project ready for upload, I will start a thread on it. it looks like 13 1982 shows, and about 40 1983's.
Any of those 83s happen to include 1983-08-26 Portland? My 3rd show, and what's on LMA and whatever else I've traded for are disappointing. I have a cass of partial 2nd set from back in the day that sounds better than any subsequent copy I've gotten a hold of. At the show I remember a number of stands running very high and very FOB.

Jeff, we were there taping with the 201's; I have not transferred that one yet; I'll see if I can locate it just to see what I have. when we get them transferred and processed, we will keep announcing.
Some have asked me why I want to do this with all the SBD's on LMA, but I have looked at enough 82-83 shows to determine why not? Any Jim Wise show will be "better" than ours as we were usually 10-20 feet behind his crew- they were crazy out of control for those years! However, some of ours do haev some fine Beyer sweetness!

90% isopropyl alcohol or more nothing less and certainly not rubbing alcohol, as they add all kinds of stuff to that. Use it on pinch rollers, capstan and heads.

Clean after 4 or more tapes, maybe more depending on how what the tape leaves behind. I use ear swabs.

I also have some rubber revitalized that can be used on belts and the pinch rollers. But you have to let that soak in overnight. Afterwards, I give it a light cleaning to remove any left over residue.

Thank you so much for this info. I was wondering about the pinch roller rubber stuff.  I think I will seek some out. I found these nice swabs via my job that are for tape heads, printer parts etc.

Everclear works well to clean tape deck heads and a pint will only cost you a few bucks. A demagnetizer works well also, but you need to be careful when using it.

I'm being surprised by many of these Beyer recordings. Back in the day, possibly due to playback limitations, we though the Nak's were "better" sounding, and we had improved our overall approach, mic and deck wise by 1983, so many of these 1982 tapes never got too much play. we always made several first gens on one pass once we got back home, and the masters were rarely, if ever, played after that.

As was said above, 99% Isopropyl on the heads.  I won't touch pinch rollers with anything other than pinch roller cleaner here at the studio (for both my reel to reels and the cassette decks).  I've seen alcohol dry out rubber rollers and they cost too much to have rebuilt these days.  I'd recommend a dedicated pinch roller cleaner--you can find a few options via google.

Clean every few passes, as needed.  Baking cassettes from that era probably won't be needed.  Only if you see significant oxide residue and tapes are literally gumming up and stopping (at which point you've probably done some damage....)

Speaking of cassette decks, I've been building this rig for the past few weeks.  It'll be a fun one.

Thanks for the info on baking Heath. My buddy who was part of the Jerry Moore JGB project says they had to bake several of his tapes.
Most of mine so far, almost all Maxells, do not seem to shed much.
Great photo, what is the model Tascam there, and how much do they retail for?

Those are Tascam 122 mkIII - industry workhorses.  I used to have racks of Nak MR-1s, but they just prove too delicate for the amount of use they see in our facility.  The Tascams hold up much better.

Prices are all over the board depending upon condition.

Reviving this old thread as I have been doing a bit of cassette transfer work these days and am about to do more. I just bought via Amazon dedicated pinch roller cleaner with tape head cleaner, the brand used to be the studio standard- SR Audio- has now renamed itself Audio 456.

I am going to add more about head cleaning next. Anyone have favorite brands? Post them here.

Intraclean S-711 if you can find it.  Hands down the best head cleaner and banned for causing cancer.  It is a heavy chlorinated hydrocarbon.  It smells sooooo good though.   :cheers:

Try American Recorder technologies.  805.527.9580 They sell the new version of the Intraclean solution head cleaner.  Look for one of those TDK cassette head
Demagnetizers that you just put into the deck and push play for several seconds.  They may have that too.  I buy my swabs for cleaning at Markertek.
