Default Tube pricing from 1981

I stumbled across a Zenith MSRP list from 1981; close to the end of production I would think. It was interesting to me and I thought I'd share.

There are very few tubes that seem cheap, adjusted for thirty years of inflation. I didn't see any that I would have bought a case of then for sale today at a profit.

7591As for $13.60?

Perhaps some transmitting triodes and 300Bs would be more exciting, although I bet they were not cheap then either.

6GM8/ECC86 at $11 each would be worth ~50 now since they are unobtainium I think.

Wow, they've really come down on price. They were making ~50 each on ebay etc.

Global recession is some good after all!

It seems a fad has ended. The 6GM8/ECC86 is a nice enough tube, but it really is for specialty low voltage situations. For instance, you can make a decent buffer with the type around a 25-0-25 bipolar PSU. However, I can't see designing for it, from the ground up.

It was popular for low voltage aikidos - broskie had a design specifically for them. There was another variant with a mosfet headphone output. I built one of each and they sound very good - the headphone one is one of the best headphone amps around.

Basically low voltage tube pre using standard easy to get transformers.

I see even the russian equivalent 6N27P has come down a lot in price.They were making 25-30$ each.

The Telefunken EF86 still seem to be pricey. Collector stuff, apparently.

edit: I mean ECC86. Duh.
