Kustom Signals was the spin off that largely created the market for portable, police operated speed enforcement radar ...

And, if memory serves, Kustom also sold radar DETECTORS, thereby capturing both ends of that "cat and mouse" market.

It makes it easier if you know what the device doing the measuring is looking for.

The original Fuzzbuster?  Escorts designed by Dave Valentine were all the rage when I was a kid in the 70's

I still use a Valentine 1.  Best there is.

I ran lots of carvers 1.5s back in the day.

HORRIBLE pin 1 problem.  That, of course, I didn't realize until after I stopped using them.

I would often spend hours trying to get the buzz/hum out of the system because of that.

I loved the weight though.  VERY light for those days

I remember one place I worked at, the tech guy put bypass caps on pin 1 to the carvers so the lifted pin would still ground out the rf whine.

Been to touch with George Piburn..who was out with Kevin McManus in 1980 on ZZ’s Deguelo tour...awaiting some pics

Combine Carver 1.5's pin 1 issue with the mostly ineffective Yamaha 2031 graphic EQ that also had a pin 1 issue and POOR!, hours of frustration chasing the hum out of the monitor rig (don't ask me).  One never got rid of enough of it for one to hear the stuff the output choke didn't get...  Other than the weight I really didn't care much for Bob's amp as a professional user.  It was brilliant in a number of ways, but...

A couple years ago a friend said something to the effect of "yeah, no ground loops with digital stuff, remember back in the day..."  The difference is not just ones and zeros, it's that manufacturers have upped their circuit design and layout game (maybe the AES standard helped!) and they're not designing problems into their products they way they once did.

Hmmm. I dunno. It's been my observation that all of the time we used to spend chasing ground loops and other buzz and hum issues has been replaced, second-for-second, with tracking down IP related issues and other forms of "this not talking to that". YMMV

The problem with their pin 1 was that the connector was attached to a circuit board and the ground trace was vastly undersized. It was the definition of what Neil Muncy identified as the Pin 1 Problem.

We had him give a talk to our Section back in the early 80's; we started the meeting at 7:30pm and were immediately fascinated by what he was showing and telling us. We followed him as he led us here and there in a fascinating way. At some point we started to think maybe it was about time for an intermission, looked at the clock, and it was after midnight!

After seeing that, I started rewiring all my Carver amps; it was as simple as severing the ground trace at the connector and running a short wire to a chassis ground point. No or few problems after that.

Those amps started routinely dying after the turn of the century so they got replaced.

I used more 2.0's and PT-1200's (model #?, same as the 2.0 but lower sensitivity number) which were lighter yet than 1.5's, but you're right about the weight of either; they beat the crap out of PSA-2's.

(OT: FWIW the 4 channel Behringers are better than the lighter Carvers in the weight department, sound quite a bit better, and are vastly cheaper, while being about as powerful. Haven't seen a pin 1 problem yet.)
