2 ideas: 1. the obvious intermitent solder connection somewhere. look at the solder side of all boards with a magifing glass (or optivisors)...look for a grey concentric circle around the joint...this is the telltale sign of something that needs to be resoldered. if you are good with a soldering iron, go ahead and resolder anything that looks suspicious. 2. most (if not all) tape decks have a large multiple switch that selects between recording and playback. there are many contacts in this switch, and they often need to be cleaned. get some cleaner/lubricant inside there (even if you have to cut the corner off the housing with angle cutters to get it in)...this is a common problem with cassette decks, and i believe, reel to reels as well. deknow >> yikes! >> any of you who could actually recognize an open reel of tape might >have an >> >> opinion on this one. >> tascam 38 1/2" machine: deck is otherwise very clean and in good shape. >> tape track 2 often - but not always - will not return output to the >> console. >> our testing kitchens have confirmed the following: >> - it's not the snake >> - it's not the input channel >> - it does not seem to matter if noise reduction is engaged or not. >> - swapping the rec/repro card with that from another track changes >> nothing, >> the problem does >> NOT migrate. >> - i can see the meter moving - it just doesn't send much signal. >> occasionally i get about as much output as a bad case of crosstalk. >> - some nights 2 is fine. some nights it only works for a little while. >> some >> nights, it takes the night off. >> - i can't think of a single thing that's changed in the setup EXCEPT >that >> the heat in my apt. came on with a vengeance this year, and it was >like >> death valley in there for awhile - i have since turned the heat in >that >> room off, the problem continues intermittently. >> your suggestions, commiserations, prayers and special hoo-doo effects >are >> roundly invited. >> replies off-list are just fine. >> a:
