Hallo Leute, habe einen 1.3 NZ restauriert und jetzt ist als letztes der Motor dran. Wie ihr hört sägt er leicht und läuft nicht wirklich rund im Leerlauf.

Dazu habe ich dieses schleifende Geräusch dass ich nicht richtig zuordnen kann und natürlich dieses sehr laute klackern. Ist das ein hängender Stößel?

Habe die Drosselklappe schon gereinigt, abgedichtet und die offensichtlichen Unterdruckschläuche ersetzt. Wenn ich den Stecker an der Drosselklappe abziehe, bleibt der Motorlauf gleich. Habe dort 5V anliegen.

Freue mich über jeden Tipp!!!

Ich höre nach wie vor sehr gerne CDs, besonders seit dem der Vinyl Markt so teuer geworden ist.
Denn das ist das was ich an der CD so liebe: Sie ist billig.

Habt ihr Tipps für Läden mit guter Auswahl und fairen Preisen? 💿

Hi guys! After I brought back a broken CD50 as well as my Beogram 5005, I wanted to overhaul my Beomaster 5000.

What are the usual restauration steps? Which parts should I swap/check?

I will do filter caps for sure and also heard that the relais for audio muting and power supply wear out. When the Beomaster is in stand by I still have hum on some speakers.

Thank you guys!

Hi guys, my Dynacord Twen II has a pretty bad (what I think) 50Hz hum in the preamp section.

When I short the input jack, the hum goes away completely. When I switch V1 and V2 the hum stays consistent (they are both ECC83s). The hum is reduced when there is a jack plugged in. Of course it does respond to Volume knob and goes away completely when turned all the way down.

What I already did: Changed caps, tried another input jack, got rid of input no2, resoldered all the connections around V1 and preamp, resoldered ground connections, measured between tip and mass (2,8 kOhm), unsoldered input cable on pin 7 of V1 (noise gets louder), poked around with a stick (only pin 6 and 7 respond to ma poking - grid and anode).

Im a beginner at repairing this stuff and chasing down hum, happy for every hint. It seems to me that there is a problem with the grid. I dont want to throw in new tubes unless Im not certain mine are blown. Thank you guys in advance!

Hello friends! I picked up this broken SK-15 and wanted to get a shot in fixing it.

First of all volume is super low, from the three voices I can only play the organ, the other two are just static noise. Organ seems to shine throuh no matter what I select. Voice control barely works. The keyboard is behaving in a way, which is hard to describe. Pitch is somewhat right but it seems to play two tones at a time, limited polyphony, some keys create only noise.

I already changed cabs in the power supply section. The chips get the voltage they need. I have never went further than basic stuff like recapping ob synths. Where should I go? Is this a Master Clock problem? Luckily the manual has documentation about the chips. Happy about any help I can get!

Hi there! Me again! I replaced the big caps, all the small ones I left untouched. The humming is still crazy and hasnt changed a bit since my recap. Should I also go for the small ones? Can sb identify this kind of hum? Thank you guys, Im new to amp repair 😩🤙

Can anyone tell me the correct part number/link for that brake caliper?

I ordered the "correct" one twice and both of them weren't right (came with different mounting). Starting to loose my mind over this. Golf 2 1.3l NZ '88.

Hi there! Im not that experienced with tube amps, but I got this Dynacord Twen II which had a corroded tube and some cold solder joints. Now that its singing again I still need to change the caps and a volume potentiometer.

But I got this weird noise in the amp which almost sounds like a snare drum net, a vibrating hum responding to the frequency im playing. I stabbed all my tubes with a stick, I couldnt hear any response from the speaker.

Sorry if this is a beginner questions, just getting into it. Can provide schematic if needed!
