Default Re: DIY battery eliminator for valve radio

I fully agree. It is very frustrating because any" pair" of 1920-30 radio tubes that can be pre-amp candidates for audiophiles' subjective fetishism can command a high price on ebay. You dont have to look hard on ebay that they become collection trophies for the audiophiles.

I felt a similar sense of concern when I came across a website claiming that the EF50 was an audiophile valve. To get around the microphonics for audio use they had wrapped them in latex rubber and put them in a PVC tube with a modified base. It made me worry that an electronics restorer and historian might be trying to repair some wartime radar gear and not be able to get a valve at a reasonable price.
Wrapping them latex rubber and PVC, it certainly consitutes a SM fetish!
