Have you tested the motor outside of circuit ? Would want to make sure the motor itself doesn't have a problem before suspecting anything in the...
Generally speaking in such cases, there are 3 things that can go wrong: - the lever may be hard to turn due to hardened grease (not aware being a...
From calibrations done before on D6/D6Cs the difference between measuring directly (multimeter 10MΩ input) and with 47kΩ load is about 20-30mV...
Something isn't clear here: you stated this current spike only happens for 2 seconds at startup and then current draw goes back to normal (normal...
Yes that's it. Do keep in mind the amp may or may not be the problem. Without more measurements it's hard to tell. If you have a scope, checking...
As long as the voltages at the Dolby chip don't change, you're fine as far as the Dolby decoding goes. Read the Dolby IC datasheet myself, will...
Hello and welcome to the forum, @sebywalkman ! Regarding your Cybernet PS-101, that's very similar to the Infinity Intimate I posted here:...
In order to know for sure if it's indeed the brass pulley that lowers the W&F, you must test the same unit with both brass and plastic. Otherwise...
My preffered way to remove caps is using soldering iron, but the corrosion needs to be cleaned a bit first otherwise it will be a bit hard to melt...
See the Nippon Chemicon logo in the picture attached. The 88 E3 looks like a date code and batch number, it's probably stamped only on bigger...
The kit on ebay is way too expensive for a handful of caps. Use SMD tantalums instead, those are cheaper and can be found in 1206 package for up...
Belts you can get from DeckTech: https://www.ebay.com/itm/224456754842 Regarding the mechanism, can't see anything obviously wrong. But if the...
Other units I have restored from this series (JX70, 707, 929) had leaky caps. Not sure if on the 3000 they used a different brand that don't have...
Both DC brushed motors and 3-phase brushless motors can run in reverse, despite in most cases DC ones are not used in this configuation. This is...
That's funny, that sealed IC has only sentimental value if one wants to collect it. Is there anyone collecting NOS parts (without the intetion of...
When the head develops that ridge, it's only usable if the groove is aligned perfectly with the tape path. One scenario that can and does happen...
You can check for tape curling at the guides, but that's not very accurate since the guides are usualy a little bit wider than the tape, so there...
Yes, I am familiar with HPR tapes. There's a thread here about head height one:...
Assuming the unit works perfectly in both playback and record ? Can the bias be set to match input/output levels at 10kHz ? Would also be...
It's hard to point out what the exact problem could be. Something as simple as corrosion inside the FWD/REV switch creating a small parasitic...
