Re: Braun TG1000 playback head amplifier BRUM. HUM
Hi Raimund, "please press start, then pause: does the BRUMMM change if you switch to another speed? Does the Brumm stop? " ------on pause BRUMM still exists, no change in quality of BRUMMM during switching the speeds. If TG is in Stop mode, is there any Brumm or is then silence? ------in S...

Braun TG1000 playback head amplifier BRUM. HUM
HI the big question is if BRUMMMMM in TG1000 tape recorders is a faulty design of electronics or something has happend over the years during aging process of capacitors, resistors, transistors, etc? I have five TG1000 tape recorders and all of them have the same BRUMMMMMMM. The playback head of cour...

TG1000 silber loud pop noise during pressing buttons
hello
the early Braun TG1000 silber version does not have FET transistors usually suggested to replace in case of popping sound during pressing keys Play FF Rev Stop.
please advice what to check because I run out of ideas.
thanks in advance

hi
and thank you for the tip but I could not find anything about SPF326 transistor.
It is used in Braun TG1000 tape recorder.

Re: TG1000 (4.75cm speed) distorted higher frequencies
Hi Raimund and thank you for your answer.
Would you please show me on the schematic which RC elements in recording amplifier are responsible for EQ for 4.75cm speed and to what value to change them to lower from 20dB to 10dB for instance at 10kHz.

TG1000 (4.75cm speed) distorted higher frequencies
Hi Even at 4.75 tape speed sound is very pleasant till higher frequencies appear. All the 'sssssss' become very unpleasant distorted 'shshshshshsh' Very low recording level does not help, just adds more audible tape noise. I imagined that higher frequencies will be gently rolled off with max frequen...

TG1000 height of the tape spools
hello
What will be the proper way to adjust the height of the tape spools so the tape will be exactly in the middle of the spool?
thank you in advance for your help.
Darius
ps is it normal that motors and other parts for example rectifier bridge on control board are so very very hot?

What oil/grease do you recommend for Braun Papst motors?
Also is it necessary to take apart the motor to get to the bearings just to lubricate them?

TG1000 3sec from STOP to PLAY. how to make it shorter?
Hi
I am interested in shortening time delay between full stop from FF or REV to Play function to 1sec.
Could somebody skilled in electronics point me to the part of the schematics and give me some ideas what to change and to what values.
Thanks

hello It took me some time but I could not find in my town the right transistors so in the end I decided instead of BC340 put BD139 which I had in my spare parts.

Re: TG1000 2-track DAMAGE CONTROL
So the latest news. When all 3 speed buttons are off the capstan motor moves freely if I turn it with my fingers but with any speed button ON, I feel strong magnetic field and can turn it a little bit and it jumps about 2mm forward. My guess is that maybe one of the transistors (BC340) attached to t...

Re: TG1000 2-track DAMAGE CONTROL
hello Gerhard
thank you for the suggestion
I am aware of necessity of speed button being pushed in.
no reaction to speed button change.
I am just wondering why the capstan motor is slightly warm after few minutes.

ps. I do a lot of reading about TG1000, just very excited about my new toy.
