Beomaster 1600 Wheels and Belts
in BeoMaster · Dec 18, 2022 12:23Hi John, yeah that sounds like a plan, I've not had any experience with 3D printing so I'm unsure of the integrity of the formed pieces, but the joint between the wheel axle and drive shaft is going to be quite stressed …
Beomaster 1600 Wheels and Belts
in BeoMaster · Dec 14, 2022 10:43Hi John As there's been no suggestions for you, I'll try to offer my thoughts. I've done a couple of these and luckily mine didn't have your problems (mine was clutches), so would it possible to glue some tight fitting p…
Beomaster 4500 - one channel only
in BeoMaster · Nov 19, 2022 10:37Hi Paul, Firstly I'm probably NOT the best person to ask for advise, I'm an amatuer that "dabbles", I've had no formal training so I can't really be of much help, but I usually start with a long good look at the boards, …
BM3500 / BM4500 similarity
in BeoMaster · Sept 15, 2022 22:07Great minds think alike Stoobie, the sticky back plastic is already on order ! (I like the mirror finish idea, that could look good too ). Tim

Non working Beomaster 4500 to give away
in For Sale · Sept 14, 2022 10:25Non working Beomaster 4500 to give away. No glass control panel, with a BM3500 "lid". It has two faults, one know to be on the FM/MW tuning board, the other hasn't been traced. There's many good re-uaseable parts that wo…
BM3500 / BM4500 similarity
in BeoMaster · Sept 13, 2022 23:13The control PCBs were found to be identical (the 3500 even had a timer pin - complete with griplet - I think that's what they're called), I put the 4500 glass control panel on and every thing appeared to work, I can mang…
BM3500 / BM4500 similarity
in BeoMaster · Sept 12, 2022 20:29I suppose the obvious question then is, will the BM3500 work using the BM4500 glass control panel - despite the loss of the timer functiom ? Tim
BM3500 / BM4500 similarity
in BeoMaster · Sept 11, 2022 09:11Hi everyone, A quick question followed by the reason. Is the only difference between a BM3500 and a BM4500 cosmetic ? I aquired a cheap BM4500 a few months ago, it had a fault with the FM/MW tuning board and another prob…

BM1700 - A few Minor Problems
in BeoMaster · Jul 25, 2022 05:02Hi everyone, following my success with a BM4500, I decided to have another go with a project I almost finished last year. It's a BM1700 (type 1701). It was dead when I had it, I needed to repair the belts, main swittch (…

2 x Beomaster 900Ks
in For Sale · Jul 11, 2022 09:51Two Beomaster 900Ks available for restoration/spares, one actually works but needs the tuning cords replaced, the other has a broken ferrit rod. The woodwork is in reasonable (restorable) condition on both and the speake…
Beomaster 4500 - one channel only
in BeoMaster · Jul 5, 2022 15:52Well . . Well. . Well . . . ! Who'd have thought it from B&O ! In my last post, I was having concerns about "Tape 2" not responding, I was looking at the PCB with the intention of replacing TR24 (BF840) with some 8x magn…
Beomaster 4500 - one channel only
in BeoMaster · Jul 4, 2022 21:32Since the update I've realised my own stupidity ! (It must be an age thing - this is what I've got to look forward to in my retirement !) I've been trying to "blame" the EEPROM/battery for not remembering the settings wh…

Beomaster 4500 - one channel only
in BeoMaster · Jun 27, 2022 20:28Thanks Christian for those words of encouragement - it helps to know I've got people 'looking over my shoulder'. Luckily I have a 'scope so that made tracing the fault easier. The IC3 (STK4151V) replacement has already b…
Beomaster 4500 - one channel only
in BeoMaster · Jun 26, 2022 08:22Well . . . . . So far I've managed to trace a stereo signal going into IC3 (STK4151V) on pins 1&18, but only one channel coming out on pin 13, nothing on pin 10! So I think I've found the culprit. My concern now is, what…
