I am sure that are at least a few folks who are using the TR7 with a power
supply other than the PS7. And I am thinking of those some are using linears.
So where and how did you gain access to the ALC line of the TR7?

Ron -
Pin 9 of the PS-7 Control connector. The 10 Pin Jones connector. Pin 10 is
ground.
Some day when you're bored, you could go in and link Pin 9 over to that SPARE
phono jack just above it.

Oh, and the VOX relay contact is right next to it on Pin 8. A REAL relay contact too, none of this
wimpy reed relay stuff. :-)

You need a Cinch-Jones S-310 CCT plug and connect the shield of the
alc cable to pin 10. Connect the center to pin 9.
Plug into the matching 10 pin PS7 socket on the rear of the TR7.

Or surface mount transistors.

Perhaps they though the rear panel of the radio was getting too cluttered. More
puzzling/annoying to

BTW I am not blaming the companies. Unfortunately, we do this to ourselves
with the way we invest, shop and consume.

Gary,
Any ideas on where to put another RCA jack for the VOX relay? Maybe steel the
counter input?

Hi Jim:
Those Din types are really no harder to find than the multi-pin Jones
conn's !

I'd be inclined to use the fixed 'line' AUDIO jack. The counter input can be
handy, obviously as a
counter, but also as a good quick troubleshooting tool for the radio.
Or just drill a hole for another RCA jack, or even a mini earphone
Yeah, I understand engineering to price points. On the smaller rigs, it's more
an issue of availabe real estate on the rear panel. Doesn't mean I have to LIKE
it... :)

Yes, that is a good way to speed up the amp keying. A half mA shouldn't be a problem, those lines
are 'fused' very closely, but they should survive that! :-) Saves a whole ~25 mSec!!

That's actually funny, because years ago I first heard tech calling transistors
three-legged fuses.
A corollary to Murphy's Law

Nice of them to design the device to contain the magic blue smoke, though.

Hello all,
I have a technical question. Now that my TR7 is back in business with it's
restored frontpanel, I noticed I problem I had before and had
