CD3300 high pitched squeal at the outer tracks during play, radial servo noise??
in BeoGram · Oct 14, 2026 19:55Thanks Martin, Very possible,.but from its known history and looks inside it was fairly untouched, and its beoparts kit i used to recap :) so should be fine...measured both current to the radial servo over the 4.70ohm R3…
CD3300 high pitched squeal at the outer tracks during play, radial servo noise??
in BeoGram · Sept 10, 2026 16:40It was not heat dependent, I was mistaken, i measured the frequency its spot on 5168Hz, all the time.... Does this bare any significance? thanks
CD3300 high pitched squeal at the outer tracks during play, radial servo noise??
in BeoGram · Sept 9, 2026 17:51...After some additional analysis, there seems to be a heat/time component. When the player has been switched on and playing "for a while" the high pitched noise goes away playing those end of disc tracks. I also lifted …

in Imported Content (Unmapped) · Dec 19, 2019 20:15Hi all, I had a cracked PCB exactly where craig had his ( /forum/imported-unmapped/bm4400-basket-case ) And the weirdness of the artifacts before i read his adventure and found it made me think there was issues with the …
Beovox RL140 same serial nr, but differences within?
in Imported Content (Unmapped) · Mar 24, 2018 21:31Thanks Martin, a bit strange but aslong as it have not effect on sound. I do think it was not there originally, the stickers on the back with serial etc indicate it is the original rear piece, and there is absolutely no …
Beovox RL140 same serial nr, but differences within?
in Imported Content (Unmapped) · Mar 24, 2018 21:15Hi all, I have acquired a pair of very old RL140's and opened them up for a refoam job, but then something strange caught my eye, the insides of the rear frame looked different in this matched pair (same single owner sin…
BM4400 acting up, i can't figure it out...
in Imported Content (Unmapped) · Nov 8, 2017 09:03Hi Martin, First I thought..."can't be the cause , I have done that already for an hour,, no improvement, must be something more complex.." But then I read your reply more carefully again..you write "contact cleaner that…

in Imported Content (Unmapped) · Aug 21, 2017 22:13Im back with some news. Replaced the 3055, but still nada... so i gathred that more of the pre-amp had blown... replaced TR59 and TR60 with temporary lover voltage transistors, just to see if I can get anything through h…
Adjusting Idle current on a Beomaster 3000 type 2404
in Imported Content (Unmapped) · Aug 15, 2017 09:32Using Dillen's questions from the older BM3000 posts i linked to, i verified that the 3055's of the busted channel were toast. If those became toast because the preamp blew or if the pre-amp blew because the 3055 blew is…
