Default Are 6GM8's rare?

Hi there,

I'm considering building an Aikido line stage p2p and as it's my first tube project, I thought the 24V version sounded.....safer.

My question is - are tube vendors running out of 6GM8's?

Has anyone bought any recently?

No worries; if it's too difficult I'll just try using more 'standard' tubes at HV.

Cheers

Stuey

Oh, I should have explained that I've tried a few who listed 6GM8's but were out of them. Except for one whose prices were ridiculous which I didn't try...

Cheers

The tubecad article on a 24V Aikido seems to have driven up prices and made people run low on supplies. It used to be a cheap valve but I have heard it recently going for higher prices than the ECC88 family.
If you can manage to raise the supply voltage to 100V you should get good results from a ECC88

Just plug an ECC88 in place of the ECC86/6GW8 and listen ...

You may of course compare the plate curves before, adjust the scales and .... conclude yourself !

The russian version is the 6N27P which maybe less expensive. Upscale audio was selling 6GM8s, Valvo marked boxs. They weren't cheap but sounded quite good. Check upscale web site see if they have any left.

Thanks guys.

It may be better to just go high voltage to avoid problems with finding future replacements - (and also enable tube rolling...?)

Cheers

They have become a bit more scarce - again the popular tubecad articles and the headphone amp variant has reulted in increased demand. I bought the last stock that radiodaze had - I ordered 8 but he only had 7 to send me. They do come up all the time on ebay but tend to be a bit more expensive.

I must try some of those russian equivalents - and ECC83 and even some 5751 which is a ECC 83 equivalent. It would be interesting to try.

FWIW, the 6GM8 in aikido sounds great.

I have been hunting these down for a while with no success. The only people that have these want way too much. If anyone has a line on these please let me know.
Thanks
Ben
