Your wishful thinking is much appreciated. Great crowd in this thread.
All LEDs are on. I will have my tech run through the list Ki suggested. I have all backups I ever need on my vinyl front but not on tape. Now I have to think of backups on tape front.

I'm sure your tech will be able to quickly resolve the problem. Unfortunately, while audio card spares are easy to find on eBay, the transport control cards are typically not. The only reliable source of those cards is Audiohouse in Switzerland. If anyone knows differently, I'd love to know.

The first step Ki forgot to mention is to reboot the system. The main cpu is on the Master MPU card and it has a button switch on the front edge that will reset the system. The other is the TD MPU (tape deck) and it has the same switch (same type card just provisioned differently).
Turning the power off and on does the same thing, just takes longer. The button has saved me in session before.

Thank you sir. Ki did not forget. He saw I wrote I turned on and off power earlier. My tape dealer will come to pick up my machine this Thursday.

the cousins are reunited after M15 Rifa x-cap replacement and recap motor and psu caps

Come on leif be honest .
Isnt that adjustable spooling handle on the M 15 far more practiçal / faster then the push buttons on the A 80 ?

 

[christensenleif@msn.com]

yes that single feature is very useful and were adapted in the A816 for a good reason, but the rest of the machine is slightly primitive
but I quite like it...

3 speeds is definitely better, than one, but I like the way the A807/810 do it.

Not to mention some machines with trully variable speeds.

like I mentioned earlier...on my A80RC I use EDIT spooling for variable speed
a wheel or a lever, doesn´t matter

 

[Foxbat]

Did you remove the springs?

 

[christensenleif@msn.com]

somebody else obviously did on all the machines I´ve had here....

What is this with these audiophile forums ?
One person bombards me with horns , the other with non variable speeds .

As taken from the German Telefunken M 15 manual .
For those of you who dont speak german :
Umspulgeschwindigkeit in beiden richtungen stufenlos einstellbar .

Stufenlos means stepless in english

It does not take much to look at the schematics. It is a seven-position switch. Neutral in the middle, three to the left, three to the right, as has been already shown here.

Smartly, they used a make-before-break switch, so the transitions are smooth, but you can still feel them.

But if the paper says "stepless" - what do we know?

 

[andromedaaudio]

You and fox bat owe me a belgium beer.

 

[christensenleif@msn.com]

why on earth?
same switch as I published and it clearly shows the wiper slides over the contact points

AFAIK, the springs on the Edit wheel were actually on the A80 VU and A80 R but not on the later A 80 RC machines. So no issue for spooling with the RC versions.

Okay you re right , but like foxbat stated you dont (hardly) feel any transitions, its a very nice switch .
Still take it over the studer buttons anytime
