Valve site

Confession time....    In all my time I have never ever built a valve circuit!  

Maybe low voltage HTs might have persuaded me, but all my circuit ideas and projects have been semi-conductor based. If you are interested in valved circuits you may want to visit Andrew G6ALB's site.

Valve site

G8ALB has a site that is mostly about valves. I arrived on the scene just after transistors came in and I never got to build anything with valves. The nearest I got was a stroboscope.  A VHF RX based on the 955 acorn valve, was on the drawing board, but was never made.

Valves

Facebook regularly shows memories of years past. One popped up yesterday showing a CW valve TX that G6ALB build some years ago.

He did not feel confident on the key, so I operated.

On 15m this little 400mW rig got a response to the very first CQ call from a W. We nearly all fell off our seats.

I have to confess that I have never built a valve rig. Andrew G6ALB keeps trying to persuade me.

Elector valve radio kit

Not having built valve radios (far too young at 62, HI HI!) my eyes were drawn to the latest offer from Elector magazine for a complete valve radio kit built into a neat wooden case. See https://www.elektor.com/Uploads/2011/6/Valve-Radio-Kit.pdf. This uses a low voltage valve (6J1) in a regenerative design with a transistor audio amp. At around £50 with shipping it is not cheap, but it is a complete kit. For the offer see https://www.elektor.com/extra/valve-radio.1843103.lynkx .

iPOD - 1940s style

This was posted on the QRP newsgroup today. Wonderful idea.
