Marquette Electronics

Everyone that ever worked at Marquette Electronics loved it. It was, in my estimation, the best thing that ever happened to me. I was hired at age 23 to be a field engineer – a job I absolutely loved. Back in those days we were equipped to a dual-trace 100 Mhz Tektronics oscilloscope, a Zero […]

Drone Update

So I bought my second drone, an “almost ready to fly” or “ARF”, which means basically you get a box of parts. But that’s OK, I wanted to get really acquainted with drone-building as I had several Android and Raspberry Pi projects under my belt. I knew the electronics pretty well, but was a complete […]

New Amp Build Project

A couple of years ago, I decided to build out a clone Fender Vibroverb clone guitar amp after having some success building first a Fender Champ clone (5W), and then a “Rivera era” Fender Champ II clone (17w). Years ago I had a cherished Fender Twin reverb that was the best sounding amp I’ve ever owned.

remotely-tuned-magnetic-loop-antenna-project

I’ve been interested in the magnetic loop antennas after having read how efficient they are, and in some ways are “Tesla-esque” being one of the oldest antenna forms out there behind the end-fed “Zepp” or “Zeppelin” as it was a single trailing wire which was end-fed,  and the simple dipole. Having just moved to more […]

Amps and Guitars

I got started building clone vacuum tube amps a few years ago. Its was a natual segue as I’ve worked on ham radio equipment since I was 11 and back then, everything was tube based. The amps in fact use many of the same tubes – 5Y4 rectifiers, 6V6 power beam pentode tubes. You can […]
