Temperature ("tempco") Compensation Resistors for Log Amps and VCAs

I no longer offer the Gig Ohm GΩ resistors or the PT-146 for sale but I did have to use a PT-146 1KΩ +3500 ppm I had in stock as a replacement for a failed KRL RQ-81 (Tel Labs Q81) found in a Heathkit IG-5238 AC Voltmeter with dB. Since I did a quick web check on both KRL and Precision Resistor I th...

Re: Vintage Digital Clock Circuits

Some pics of recent vintage clock restorations. Sometime between 1969 and 1970 I became interested in building a digital clock. I was about 12 at the time and began sketching clock circuits using J-K flip flop dividers. I am "clock boy." :ugeek: My brother had some surplus RTL (resistor transistor ...

Re: Entropy

Paul your bench looks very organized. I'd leave the HP on continuously. I have several and they all do the same thing until the caps reform. I've been on a test equipment and gizmo repair binge too. It's been raining for almost two weeks now so thats gotten me out of the yard and into the shop and g...

Re: Electrical Azimuth adjustment- aka crosstalk

The "bathtub" crosstalk curve is what I recall seeing in countless Hirsch-Houck Labs cartridge reviews over the years.

Yours is unique in that it shows L-R and R-L curves.
I've never seen that level of detail.

Re: Entropy

My HP400FL also does the same thing. It likes being on.

The 8060 will appear to "die" with no LCD display activity if the internal NiCds can't be charged - even when the AC power is on.

If it had a good LCD display you may have tossed a good meter.

Re: A Collection of Band Names and Song Title Suggestions.

Jimi did light his on fire at Monterrey but he used lighter fluid and lit it.... He has been copied multiple times since. I suspect there are pyro effects built into them that don't trash the guitar. OK I remember the lighter fluid now. I think "Banskying" the guitar is now essential to increasing ...

The certificate was issued 10-6 so an https request prior to that should have failed.

Re: A Collection of Band Names and Song Title Suggestions.

My wife and I harvested our habanera peppers this weekend and cut some up, and de-seeded them to freeze.
Didn't wear gloves and washed hands multiple times.
It burned for a few hours.
