In my opinion, the lack of answers is caused by a couple of things: 1. The test is too complex, with too many tracks and that random letters and...
@Mister X In my view, the head wear thing is similar to an old car (an analogy I made before): being in mint condition means it is less likely to...
This is true for all the portable recording units: TC-D5M, D6, D6C, D3. Most of these were used profesionally and have a lot of wear. I mentioned...
Looking at the schematic, the EQ is done by R8, C8, R6 (right channel) and R7,C7, R5 (left channel). Switching the EQ either keeps pins 2 and 23...
@tomtom87 Serviced units have a lot more value than just working units, it's something that I mentioned in my first post. I was actually...
@Longman I agree about playback specific music that was only released on cassettes: I have about 10-15 of those with Romanian music from late 90s...
It's not my intention to necessarily change anything, rather to see what other people's opinion is about the subject and also to express my own....
@Xenon4U2C Those BASF LH SM cassettes do sound very good for a TYPE I. I bought about 15 of them used some time ago (90min and 120min), but most...
Unfortunately, many pre-recorded cassettes did not use very high quality tape. This may not have been an issue when the cassettes were new, but it...
There is another aspect that should be mentioned, with the risk of opening up another debade: headphones. Not all headphones perform equally, many...
Indeed, people can ask whatever they want on a product. But what I was trying to point out is this: if enough people ask X on a certain product,...
I want to start a discussion about a trend that most of you already know about: the prices of old walkmans (especially the SONY brand) has gone...
Yes, the plastic part on the right should move. You won't break it if you're careful, spray some contact cleaner (I recommend Kontakt 60) and move...
The 2 small intermediate gears are not present in the design with magnetic clutch, so I have to draw the conclusion that this is yet another...
Some updates: it seems the EX631 and EX650/652/654 all have the problematic clutch. Will be added on the list. @Emiel if you know more similar...
@Mighty Mightor I will be looking in the service manual to confirm if this model has the problematic clutch. However, from the video posted, it...
@Mister X can move it there. As a sidenote, have you tried spraying some contact cleaner (like Kontakt 60) into those pins and move them back and...
The 2 components are zener diodes placed in parallel with the output to clamp the output voltage swing, possibly to protect the included...
In my opinion, given they state it's WRMS, that's the maximum accepted figure for wow&flutter, but in general they expect lower than that. I think...
Do you have the schematic of the unit ? I would like to see what purpose those 2 diodes have.
