Hi Phaseblaster. Thx for the video. Used it this morning step by step and healed my 690es, and it is working fantastic again.....hoping for the next 30 or so more years😊
Great tutorial. Thanks to him, I healed my TA-F590 ES yesterday. The source selector was also very dirty. After cleaning, the amplifier sounds like it got a second life. Thank you and best regards :).
thank you for tutorial, useful. for another homemade engineers : make a note of shaft position ! and good idea to check position of selector before soldering .
by the way, could you explain one thing ? I've tried to adjust bias ( should be 24 mV after 10 min after warming up - in service manual) and noticed that after 10 min I have 24 mV, but after 20-30 min, when elements became warmer, the voltage is 20-21 mV. is it critical ? I have no experience with amps, unfortunately. thank you in advance.
I tried doing this but may have messed it up somewhere in the process. Should all 3 wipers face downwards like shown at 2:17? Right now the motor doesn't run when I try to change inputs. Only the lights change.
As far as i remember the motor axis is keyed, so as long the wipers face in the same direction, you should be fine. But i don't know why your motor isn't turning. Maybe there is a service manual explaining the circuit? I'd check the solderjoints on the motor first.
Hmm, i wouldn't recommend it. You could try to get some cleaner through the underside of the switch. But you should then move the switches to clean the conductive tracks. But that will not be possible with the motor connected. I think desoldering is the easiest an most reliable way.

Hi, thanks! That sounds great! :-)

Thanx for video!!!! I hope my F870ES will be working :)
my Ta--f690Es sound bad low gain and dirt sound this operation will help?
Great video, thanks! Tell me, what is the output voltage on the transformer?

@@Phraseblaster I fixed it - it was a cold solder on motor, thanks
This is a great tutorial. Is there another way to clean this without desoldering the board?
Hmm, i wouldn't recommend it. You could try to get some cleaner through the underside of the switch. But you should then move the switches to clean the conductive tracks. But that will not be possible with the motor connected. I think desoldering is the easiest an most reliable way.
Great tutorial. Before you start, do you need to set the input selector in a specific input like phono or tape 1?
As far as i know, this shouldn't make a difference. But the wipers should face the same direction when you reassemble the switch.
