beomaster 1000 ( type 2317 ) restoration & improvements?
in BeoMaster · Aug 13, 2024 20:45That is definitely the way to do things...incredible. What software are you using to parse the signal & generate those graphs? Have you ever gotten a flat result out of a RIAA preamp circuit? As far as restoring the Beom…
beomaster 1000 ( type 2317 ) restoration & improvements?
in BeoMaster · Aug 13, 2024 17:16Wow!! That's quite amazing! I wonder if testing it right after the RIAA & before the rest of the circuitry would be the best way to assess? Otherwise tone controls, noise & interference from other things in the circuit w…
Beomaster 1000 - stereo decoder board compatibility
in BeoMaster · Aug 13, 2024 05:11Can't help you, but good luck! I was glad to see the FM board was still in my 2317, plus the schematic inside the chassis folded up in an envelope. How cool is that? Even though I'd found a PDF online.
beomaster 1000 ( type 2317 ) restoration & improvements?
in BeoMaster · Aug 13, 2024 04:52Hey those are interesting, thanks! I can't figure them out though: are the 2 colors the left & right channels? Or is one of the colors supposed to be the RIAA baseline? Because it doesn't appear to match between the 2 im…
beomaster 1000 ( type 2317 ) restoration & improvements?
in BeoMaster · Aug 12, 2024 16:56I've seen restorations where new & better tolerance parts have been used to make the RIAA circuit more accurate, as well as improved the phono preamp. So I was wondering if anyone had done that with the 1000
beomaster 1000 ( type 2317 ) restoration & improvements?
in BeoMaster · Aug 10, 2024 16:50That is GREAT info, thank you! I won't even power it up before working on it: I found reference that one of the caps in the power supply tends to explode. So I'll do all that before plugging it in. Guten tag!

in BeoMaster · Aug 9, 2024 15:58I picked up a beomaster 1000 type 2317 & want to restore it The search function on the old archived forums doesn't seem to work for me, so asking here: has anyone restored one of these, and if so are there any tweaks/imp…

5500 master ctrl panel round dial repair?
in BeoMaster · Aug 21, 2023 04:38Ah: found this thread on the archived forum, looks like it's the microswitch as the unit doesn't respond when I spin the dial: /forum/the-workbench/repair-on-a-master-control-panel-5500
5500 master ctrl panel round dial repair?
in BeoMaster · Aug 21, 2023 03:56Hi, the round spinning dial on my master control panel 5500 has stopped working. All other functions & buttons work. I opened it up & tried 99% iso swabbing the 2 contacts that touch, when the dial is spun either directi…
Beogram 5500 CD player runs hot
in BeoGram · Nov 29, 2022 12:21I just realized I'd started a thread about this previously; I thought it was on the old forum for some reason. The big cap I ordered was too tall to fit in once I swung the PCB back down. Oops. Will have to order a short…

beogram 5500 turntable repair, gear disassembly?
in BeoGram · Nov 23, 2022 13:34I tested the regulator compared to a new one, and thought it was bad. I'd like to kick the sadistic engineer who designed the regulator mounting system in the groin!! What a stupid setup. Why didn't they just screw it do…
Beogram 5500 CD player runs hot
in BeoGram · Nov 23, 2022 06:30My Beogram 5500 CD player gets very warm on the top, towards the left rear of the unit. Right above all those capacitors underneath. I just replaced all but one of them, and it's still getting quite warm. I have never ha…
beogram 5500 turntable repair, gear disassembly?
in BeoGram · Nov 22, 2022 16:51So far I've replaced the 2x 10,000uF caps in the 5500 amplifier, and most of the big caps in the 5500 CD player. The 4700uF I ordered was too tall for the CD player PCB to close down again ( doh!! ) so will have to order…
beogram 5500 turntable repair, gear disassembly?
in BeoGram · Nov 13, 2022 19:06Does anyone know if there is a good explanation of how to assemble the gears in these TT's anywhere? I didn't find the service manual very clear. Or a method to test the mechanism before powering it up? Thanks!
beogram 5500 turntable repair, gear disassembly?
in BeoGram · Nov 11, 2022 17:45Nice! I was examining the 5500 TT board & saw the - leads were all tied together, but the CD player was tougher to figure out. It almost looked like a multi cap can. I will make sure to add some support, so they're not j…
beogram 5500 turntable repair, gear disassembly?
in BeoGram · Nov 11, 2022 02:15I can't seem to find those "star solder" caps anywhere. the 1000 uF 40v one in the 5500 TT looks like it has 3 leads? I did find this, but it has 5 leads: https://www.digikey.ca/en/products/detail/kemet/ALP22A102DD200/13…
beogram 5500 turntable repair, gear disassembly?
in BeoGram · Nov 9, 2022 01:57I am going to recap the 5500 CD player & 5500 amplifier too, while I'm at it. Pretty sure the CD player has a couple of those "soldering star" electrolytic capacitors. Funny, I've never heard of them. They appear to just…
