Braun TG1000 playback head amplifier BRUM. HUM

#1 Beitrag von helloradio » 22.03.2017, 19:06

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 course has brummklape.
I replaced playback head with 100 Ohm resistor and the BRUMM was lower but still there and very disturbing (playback head is very sensitive, as we know what no brummklape cand do for buzzz)
All five TG1000 machines behave the same, BRUMMmmmmm.

It is hard to imagine that Braun allowed TG1000's to pass quality control and leave the factory.

So maybe some changes in playback amplifier will cure the problem.
Any ideas or solutions?

Greetings for all Braun lovers.
Darius

Hi Darius,

please press start, then pause: does the BRUMMM change if you switch to another speed? Does the Brumm stop if you have no speed selector pressed?

If TG is in Stop mode, is there any Brumm or is then silence?

What can you hear if you Switch to Vorband?

Regards,

Raimund

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 STOP no BRUMM, just silence.

What can you hear if you switch to front band?
-------- this part I do not understand, what is the front band?
Regards,

Darius
