More STuff!

Ok I went to look at that large pile of recorders; and brought 4 home. First I passed on the Revox A77s... they were all nonfunctional. If anyone wants/needs them for parts PLEASE let me know, I would gladly send them on for the cost of the shipping.
I did grab the two Studer-Revox PR99s - I found a manual for them and one of them did power on , hoping to come up with one functional unit out of the parts. Some pics of one of the PR99s:















Looks like it is going to be a major project on these.

The Teac A-3070 turned out to be in fair shape - you can see from the pics that the "stainless" front panel is heavily stained. The heads look quite good (haven't figured home to get a good picture of them yet, the shroud doesn't seem to be removable and they are WAY up in there! Unit powers on and teh amp section works well, only a little bit of static from the pots. The transport is anotehr story - the capstan spins, but that belt is all but gone, the other belts look just as bad; so I guess I will be callings TEAC/TASCAM to see if those parts are still available. See pics below:













Lastly I found the recorder below, a Sony TC-650:







Haven't had any time to check on this unit, appears to be a strictly consumer deck - maybe it can replace my dying Pioneer RT-707.

Slide a white index card up against the machine and under the heads. Then take a picture of the heads. The light will reflect off the index card and you should be able to get a good shot.

From looking at what you have, I suspect that all the machines are probably 1/4 track consumer format. I notice that the PR-99 is 3 3/4 - 7 1/2 speed rather than the more common 7 1/2 - 15. Because of the speed I suspect it has 1/4 track heads installed. Am I correct on that?

They are all a worthy project to mess around with.

1/2 track heads; it is calibrated NAB standard. In all the paperwork I found the original test OK sheet from STuder and the schematics - but not the operators manual. I first played it with the tape that was left one it - played loud, clear, and balanced. I demagged it thoroughly and the cleaned the tape path; all things considered it really wasn't that dirty. Records and plays back on both channels, both through balance and unbalance inputs.

A website named Village Electronics has the belt kits for the TEAC and the Sony for $15 and $17 respectively - anyone have any experience with them?
