Hello all. Due to ongoing project with large gu81m (4 of them)

http://www.diyaudio.com/forums/tube...ltage-driver-ab2-operation-gu81m-tubes-7.html

I have to part with two gems. A lucky find from a Ryazan plant warehouse yielded 2 perfect gm100. Apparently these huge triodes are NOS but without boxes. These are the largest and most beautiful tubes on the market

Photo comparison:

An externally hosted image should be here but it was not working when we last tested it.

datasheet:
Ëàìïà ÃÌ-100

The filaments test fine at 12.6v

I ask 150 euros each. Buyer pays shipping. Any method of payment is accepted as long as it is secure for both parties (paypal, bank transfer).

Can arrange specific transportation methods but was thinking EMS for added safety.

For all info please email me at J22_it@yahoo.it
telephone number can be sent through PM for added guarantee

Cheers
Alessandro

yes anode voltage can get pretty high...but lower voltage will work too (allbeit with different behaviour). I know a builder should not say this but these tubes are just beautiful to put in a showcase. I am too deep inside my project to revert to the design stage but even a nice lowe power SET could be built around such a tube.

There is a tried schematic in the gm70 yahoo group forum. The driver i am using for my 2kw amp (search gu81m ab2 thread) should work. As i said i am selling for funds. If i had the possibility i would use the gm100 (financial possibility). Obviously this project is NOT a plug&play style kit. This is diy forum afterall!
