Still looking for that damn relays board!

Thank you Wolfgang!

These decks are not mine, belongs to a friend of mine from Germany. They made a long trip to Romania and back but I could save them. With the new capacitors inside, revised drive and new belts I belive they will work many years from now.

Best regards
Paul

A little break in order to resurect two ASC. AS-2000 and AS-3001 are working great again

Hello Michael,

I have a new capacitor for that one I will replace it soon. My goals was to finish with main amp section and to find the missing relay board, maybe I can find one in Germany.

Best regards
Paul

New capacitors inside. After that I can close the main amp section. Tested on dim bulb tester it looks to be ok, no smoke, I have to test it with signal generator

Checking the output transistors in original CSV: one pair is OEM RCA, one pair is different. In my test one 2N30055 looks to be germanium type. https://i.imgur.com/ZadMfvk.jpg It is nice to have spare parts. Il use the outputs from CSV1000/1, all are RCA and are good ones. https://i.imgur.com/RUn4VA...

Checking the voltages

Thank you Heinrich. I ask that because the schematic for early model does not have that connection point.

Ready for the first start again!


It is a mistake here (connecting point encircled in blue)?

Back to my CSV-1000. As I understood the voltage for primary coil came through blue cable with 3 wires: black, white and red. Red will be the ground, connected through 4700pF capacitor to negative pole of C802. https://i.imgur.com/mcJapSp.jpg https://i.imgur.com/W2cdNvD.jpg The trimmer goes to my CS...

A half of CSV-1000 from Germany

I search every day for that board. I also found a half of CSV-1000/1 with transformer, power supply boards, rectifier diodes, power amp, heatsinks, a complete amp section I could say. I try to keep it original so I will replace the missing parts with OEM ones. I can also make a final amplifier with ...

Another board is ready. I use Nichicon Fine Gold and KL (low leakage) and axials from Vishay

Thank you for your reply Heinrich! You are right, no many Braun in Romania, Braun is not ver popular in my country, so it is very difficult to source parts. But this is not only in RO, it seems to be all over the globe. As I told before I bought and restore CE-1000 tuner without mains transformer. I...

C802 (800uF) and C805 (2500uF) are screw ones, they are expensive on Mouser and I found a cheap approach using snap-in capacitors with clamp. I bought Nippon-Chemicon for C802 (820uF) and 3300uF for C805 I have on hand. https://i.imgur.com/ctyc4fL.jpg In the cage https://i.imgur.com/tDHHnv2.jpg http...

Looking for relays board for my CSV-1000.Thank you!

Main amp board recapped
Before

After

As I said before my CSV comes without transformer, I don t know what has happened with this unit. My serial number is 10886 and I will follow the proper scematic diagram in order to restore the power supply. https://i.imgur.com/MnCOkEU.jpg I ordered a new toroidal transformer using the voltages foun...

I started to restore the amplifier dismantling all boards I have. Main amp board. Some transistors have been replaced, I will test all of them https://i.imgur.com/6Ivf2Ax.jpg Power supply dual boards https://i.imgur.com/k7Vuzlw.jpg Preamplifier board https://i.imgur.com/6lQ5mTZ.jpg The output transi...

Hi gents! My name is Paul, I am living in Romania and I repair or do restorations of vintage audio. A few months ago I bought a defective Braun CE-1000 tuner, with no transformer but I manage to make one graceful Petra Toroid from Iasi. I changed all electrolytics capacitors, few lamps and the tuner...
