Test R2R Before Making Adjustments
If you are new to R2R, it may be best to test more functiions and other tapes before starting making adjustments. Make notes of results so further help can get specific to each separate problem. Note each side separately, they have separate criteria and adjustments.
Tape path, reel tables, tension rollers, auto stop arms, pinch rollers need to be freely moving at least. Proper cleaning and oiling can be done when you are more knowledgable, which will not take long.
Often the ends of old tapes are brittle, that may be your only problem. Put your valuable Abbey Road aside. Get a newer, strong tape onto the machine, hopefully blank to avoid messing up a tape with value. If necessary, on a blank tape, cut off any old ends of the tape until you get to strong tape.
Fast Forward for awhile, half the tape, go quickly to stop. Does it stop promptly without tape getting loose on either reel?
Hold the reel and pull back on the tape on the take up reel, see if it is packed snugly, not loose where it slips back. Not excessively tight onto the reel, compared to some pre-recorded ones that you may have acquired.
Fast forward all the way to the end, where the weight of all the tape is on the take up reel, stop, any difference? How is it when it comes off and is spinning and whipping the end of the tape. Does your machine have auto stop? Is it turned on? How does the take up reel stop? No real problem?
Repeat, using rewind direction.
Next, does your machine go directly from FFWD to REW? If so, get it going and try it. In both directions.
Next, try everything at normal speeds.
If lucky, most will be generally ok, which means you need to learn how to splice leaders onto the ends of tapes.
Until you learn that, valuable tapes, like Abbey Road, can be wound back at play speed, avoiding stress.
All tapes should be stored at normal play speeds, not at ffwd or rew speed. You can also stop trying to ffwd to favorite songs until you know all is well.
