Re: VR2023 with bad tape path stability

maybe it fell down? is the whole 'microworld' still correctly fitted in the chassis? last thing i can think of, is the cassette positioned correctly on the supporting points of the deck? normally this is only an issue with the later generation due to a split plastic cassette guide pin. the older on...

Re: VR2023 with bad tape path stability

there's no issues with optocouplers for sure, as it work "correctly" if we except the bad tape path and the hard point in the head drum. as i said, it was in threaded position when i got it, and the cord was already out of the pulley, i forgot to say that :D but because of bad solder joint...

Re: VR2023 with bad tape path stability

hello :) i'll check pulley at the back, i didn't think about them. the cord was out of a pulley, but on the right side (so not the faulty side). it was in threaded position when i got it, easy to put the cord back in place. don't know why it jumped out, but i guess it was when solder joints went bad...

VR2023 with bad tape path stability

hello, a friend of mine asked me to try to bring to life a VR2023 (well, actually it's a B&O 8804V). the first issue was a crazy clicking reel brake solenoid an no operation of any motors, was an esay one > missing +12Vb due to broken solder joints on a rectifier. but now it live again, the mech...

Re: Philips VR969 no HIFI sound, just mono

to be sure heads or rotary transformer have no defect, the best thing to do is probe the HI-FI FM enveloppe with a scope. then you'll know where to go. the last VHS i had not playing HI-FI (a combo HI8-VHS sony deck) was an open coil on the lower drum, due to a glue debris crash. sadly it happen tha...

Re: Philips VCR

if it did play correctly sometimes, maybe it is simple as a very clogged head tip, as gromsoud said. tape itself may also be the cause, as depending of a lot of things, the tape binder may become bad and easily clogg heads. and for some reasons, there's always one head more sensible to tape debris t...

Re: VR2334/F tracking "fight"

[edit: just played your video, this sounds more like a slipping capstan pich roller during recording, you cant repair that, maybe digitise the tape and try to edit out the disturbances] that's exactly the problem with this particular 2334. it's not the tape, that's the way the capstan is drived whe...

Re: SVR 4004 (ITT 241 clone) from hell

seems it was not. i've swapped motor control board, it get back to normal. but when i put back the original board, it worked too :mrgreen: maybe a contact issue. i also see something else on secam variant which couldn't make them play VCR-LP tapes with color. grundig used another transposition frequ...

Re: SVR 4004 (ITT 241 clone) from hell

second svr in hand now :) i don't even bothered to plug it first (the seller already did it, as it was owner since 2020). so i automatically replaced UA723, switch PSU to 240V, then plug, and absolutely no clock at all but it power on. press on play, aaaaannd drum and capstan motor were going full t...

Re: SVR 4004 (ITT 241 clone) from hell

yep, i confirm i have the 4 heads ready drum. i saw one day a website who talked about a SVR (or VCR, don't remember exactly) 5000 prototype, who had the ability to play them all. this explain a lot indeed. the drum i have look like an original assembly, as the blue glue on the screw for the "a...
