Problems with a Pioneer CT-F1250 cassette deck
Hello all,
I recently rescued an old and beautiful Pioneer CT-F1250 cassette deck from a friend's trash heap! It was in great shape but appears to need some work to bring it back up to spec again. Most seriously, there is a large power resistor (7W, 12ohms) on a vertical board that overheats (to the point of smoking!). I believe this may be related to the quartz lock circuitry, because it only happens during playback and record, and the circuit board has one section that is labelled "pulse count". The second issue that it seems to have is that the tape calibration doesn't seem very stable -- the ideal setting for each knob (bias/level/eq) seems to fluctuate over time, even over the course of a calibration run. Can anyone offer any hints and tips in troublehsooting and repairing one of these grand decks? Or possibly someone willing to share a copy of the service manual? It is in fantastic shape and I'd hate to see it go to waste! Thanks in advance, Mike |

If it's faulty and drawing heaps of current, you should be able to feel it getting warm. -- http://www.ratestogo.com/guest.asp?id=746183 |

Except if it's really shorted, the resistor mentioned is toast long before
the motor gets hot. One could just disconnect the motor and see if the resistor stops heating up. Mark Z. -- Please reply only to Group. I regret this is necessary.

Problems with a Pioneer CT-F1250 cassette deck
I have 2 even older pioneers -a ctf-1000 (3 head, blue flourescent VU
meters) and a ctf 9191 (I think those are the models, dont have them nearby). In the former, the motor driving the spools was faulty and in the latter the play solenoid drew too much current and blew a transistor in its feed. Dont have a service manual unfortunately. Not familiar with your model. Sounds like a nice bit of kit. Does it have the blue meters also? Good luck Ben (Mike Lee) wrote in message om...

Problems with a Pioneer CT-F1250 cassette deck
Thanks both of you for the feedback. I will try disconnecting the
motor and seeing what happens. Strangely, though, I'm fairly certain that the resistor heats up only during playback and record ... and since the capstans are always turning, and the hubs turn for all transport modes including FF and RW, it doesn't seem likely that the motor would be at fault. But I will try it anyway, and post back here with the results... "Mark D. Zacharias" wrote in message ...

Yup, it does have the blue meters. According to the silver pioneer
website, ths was their flagship deck in 79 and 80 ... a 3 head model with tape calibration facilities. build quality is strikingly rugged ... I've seen receivers with smaller transformers than the one in this sucker! Still have my fingers crossed that it will be a relatively simple fix to get it up and running again.

Problems with a Pioneer CT-F1250 cassette deck
Mike,
I too have a Pioneer CTF-1000. This is the model that was a step down from the 1250 and had the blue fluorescent VU meters. I purchased it new in 1979 and used it for many years. As I recall, it had a problem right out of the box with clicking and popping noises during playback, but this was due to a missing ground wire that needed to be added in the field due to a poor design. I had no other problems and it worked pretty much flawlessly for 10-15 years. Eventually I had trouble with the drive belt (in play and reverse FF) slipping so stopped using it. About a year or two back I went in and replaced all the rubber (3 belts IIRC, idler) and it started working again although the original grease that was used had stiffened up due to lack of use so it was being a bit finicky. Unfortunately, it does not get much use anymore since we have gone pretty much 100% to CD-ROM media. I agree the unit is worth salvaging ... Bob "Mike Lee" wrote in message ...

You have a fine collection of pioneer stuff there!
However I have to say that your site would be a lot better without all that right wing jingoistic warmongering crap located in the 9-11 /flag section, especially those sections that link saddam Hussein to Al Quaeda etc etc. Even more so since that has been proven as Bush Junta lies. Personally, I would distance myself from such spin. respectfully yours Ben "John A. Weeks III" wrote in message ...

If you're still interested, that resistor is in the pinch roller solenoid
ckt. There should be a transistor wired in parallel to that resistor which is turned on for a short time when the solenoid activates to give a current boost to pull the plunger in. When the transistor is off the resistor is in series with the drive transistor and the solenoid. Could be the boost transistor is open leaving the "hold" ckt to pull in the solenoid. If the pinch roller isn't getting enough tension against the capstan that could explain your other problem. Or it could be a worn head. tw "Mike Lee" wrote in message m... Hello all, I recently rescued an old and beautiful Pioneer CT-F1250 cassette deck from a friend's trash heap! It was in great shape but appears to need some work to bring it back up to spec again. Most seriously, there is a large power resistor (7W, 12ohms) on a vertical board that overheats (to the point of smoking!). I believe this may be related to the quartz lock circuitry, because it only happens during playback and record, and the circuit board has one section that is labelled "pulse count". The second issue that it seems to have is that the tape calibration doesn't seem very stable -- the ideal setting for each knob (bias/level/eq) seems to fluctuate over time, even over the course of a calibration run. Can anyone offer any hints and tips in troublehsooting and repairing one of these grand decks? Or possibly someone willing to share a copy of the service manual? It is in fantastic shape and I'd hate to see it go to waste! Thanks in advance, Mike |
