The procedure of demagnetizing the tape path is as follows: Make sure no magnetic sensitive tape material or i.e. electronics, like CRT screens, speakers, other tape decks etc., are near by. Make also sure the tape deck is OFF power and that there's access to the full tape path. Make sure that the tip of the defluxer is covered with rubber/plastic or similar material. Take the wand type defluxer and power it up at a distance of 1,5-2 meter from the tape path. Approach slowly the defluxer towards the tape path and when getting there, make sure not to actually touch anything in the tape path with the defluxer. Move the defluxer slowly from left to right over all metal parts in the tape path as slowly as possible in small circling movements. When the defluxer has passed all metal parts in the tape path, without touching any of them, you just as slowly as before, move the defluxer away from the deck to the position 1,5-2 meters away where you original turned on the power of the defluxer. Let the defluxer touch a potential magnetic material at that position just before you turn the defluxer off. This procedure is NOT possible to follow with the cassette shell demagnetizer type. The cassette shell type demagnetizer is way less powerfull, will only have the demagnetizing field above the central tape head and it will even touch it. It will only be able to operate with the deck OFF power if the deck is one of the "Piano Key" decks. I advise NOT to use cassette shell type demagnetizers at all. If the defluxer gets extended hot, you need to end the procedure in the described secure way.

@@mikek3818 I am afraid to make demagnetization as very stong fileds may eventualy induce too strong currents/voltages in heads. In case of cassette decks heads windings are very delicate. In my practice I usualy use transformer solder gun (fast and convinent) for servicing but never observed magnetization of head. But I care not to use tip very near to front of head. We need to remember that fields from recording amplifier are way stronger, are shut up/down sharply but they do not leave residuum.

That'd considered laboratory grade Isopropyl, best of the best. And regarding cleaning pinch rollers with 91% or 100%, if the rollers are just lightly dirty and one or two passes gets them clean it won't harm them. 91% and up evaporates in seconds, hardly long enough to dry out rubber. You would need to soak them overnight to do any harm. Don't sweat it for regular light maintenance. Heck, even a heavy cleaning, like when you get a new used deck that's really dirty, is fine just the once. Just make sure to clean it once a month or so so they never need more than a light once over and never will there be any problems.

How to clean a tape path: Use 99% isopropylalcohol on q-tips. Evaporation time of 99% isopropylalcohol is so fast that no harm, whatsoever, is done to any rubber. Been doing so since the 60s without any damage in private and in studios as a master recordist on analog tape decks. Clean all heads, capstans, tape guides and pinch rollers. Just as shown in this picture: Using other chemicals than 99% Isopropylalcohol may damage the rubber and may desolve the glue on the heads. Use of abbrassives will for sure damage capstans, heads and rubber. Rubbing Alcohol is a common nickname for Isopropylalcohol & Ethanol. Do not use Ethanol for cleaning the tape path. Also make sure it is 99% isopropylalcohol you use. Any less percentage will most probably contain oil products, phthalats and salicylate acid. Do not use that on the tape path. People claiming that 99% isopropylalcohol damage the rubber pinch rollers are mistaken. They are usually told this by people using i.e. 70% IPA or water and soap (or soup), which are damaging to the pinch rollers rubbers. For people worried about cleaning rubber pinch rollers with 99% isopropylalcohol, here's a rubber chemical resistance chart to clarify that this is not an issue at all: mykin.com/rubber-chemical-resistance-chart-3 I have seen Butyl, Hypalon and Viton as material choise for pinch rollers. It is mostly more modern decks using Viton for pinch rollers.

Question: Some of my tapes when played on a dual cassette deck, you know the one's used for dubbing, where one of the two compartments only is used for playback, but doesn't have an erase head, but the other compartment has both playback and recording features? Well, some of my tapes sound warbled on all of my machines if I play them from any cassette compartment missing an erase head, but they will work on the other compartments that all three parts, pinch roller, playback head, and erase head? IS there something about tape decks that can also record maybe being able to guide the tape along better to prevent the warbly sound? Can't figure out why some, certain tapes all sound good in Deck B's of dual cassette decks, but sound warbled on Deck A's of all of my dual cassette decks.

I think it is good observation- earse head better leads and stretches tape around play head. Erase head makes one more support for tape. Thing which is almost never mantioned is condition of filt pads in cassettes. - The also may catch dirt from tape and build up on side ar after many years are not soft any more making one channel readout worse. Tapes stored many years in bad condition catch dew from air and fungus. They need to be cleaned as well.

@ThriftyAV3 жыл бұрын
I own a 424 mk1 (that no longer powers up). The bias and time constant of replay EQ are preset for Type II tapes on this unit, so you will have poor treble response when recording and playing back Type I. From what you described, it sounds like the noise is associated with the playback head of your unit, not the record head. I'm not sure if dbx can be turned on and off on the MKII, but if it can, you might try that out. You can also try the different tape speed settings. Also, does it occur when you record silence as well as music? NOT a blank, but a tape with silence and a bias signal recorded onto it. You could also try recording various test tones or a frequency sweep to see if there are trouble spots in the frequency spectrum. Compared to the resale value of a 424 unit, a demag wand is cheap, so certainly worth trying out. However, these old machines have a lot of capacitors in them, so if this is the problem, the fix will involve replacing caps on the circuit board.

I also used the wand type on my smartphone after slapping a neodymium magnet onto it to see if the compass gets back to normal without recalibrating. It didn't. And I tried to erase a tape with the wand demagnetizer on purpose. Didn't erase, but made it actually louder and noisy. Also tried demagnetizing a few screwdrivers. Some did demag, some didn't.

@ThriftyAV2 жыл бұрын
IF your tape head is significantly magnetized, this can erase signal from your tapes. High frequency signals will suffer the most. That being said, having a lot of play hours on a head does not necessarily mean that the head is over magnetized. On 2-head units that are used for recording, the bias signal applied to the head during recording acts to demagnetize the head in a similar manner as a degausser. On 3-head units and 2-head units that are only used for playback, heads can build up magnetism over time. This is why every owners manual for tape based recorders and players has instructions to degauss on some recommended timetable. In order to check to see if your head is magnetized requires a magnetometer (gauss meter), a tool most folks do not own. Degaussing is a precautionary measure that can provide peace of mind that you are not damaging your tapes.
