Re: Identifying some rare tubes...

 

Yes they will convert to a hi mu

Price last time I asked was roughly 2400 minus shipping to rebuild a 3cx15k . Not sure on the 3cx10k

Econco changed their warranty , now 1 year / 3000 filament hours whichever comes first.

Used to be 3000 hr filament and no limit on time to achieve.

grid" I suppose that is only possible with the 3X15 because a hi mu
grid component is available? Does anyone know the cost of a 3CX10/15
rebuild $? ballpark, I've never done it.
A couple of those tubes with flex leads are Thales ITL9-1's (low mu
oscillator tubes) I guess there is unlikely to be a hi mu grid for
them :-(
