Specifications for the YC-179???

[WA1HZK]

Does anyone have the specifications for the EIMAC YC-179? It's a special tube they MKS-ENI (I don't know who this is) and they say they cannot release specs. I have one that I would like to prototype my amp with but I need to know the Fil. Voltage & current along with how scroatful the grid is?
Any Data Out There?

Same as a YC-156, same as a 3CPX5000A.  I tried to get the data sheet for the '179 from Eimac, they wouldn't do it.  He told me it was the same as a YC-156 but tested to tighter tolerances.

I have a datasheet for the '156.  If you need it let me know:  n2bc@stny.rr.com

What does it look like? I bought an EMI amp at hostraders once then quickly resold it to Dale the P.M. of the north. I removed the MRF150 driver section. He really wanted the tube socket assembly. It had a socket that looked 4CX5000.

I've seen the surplus guys selling YC tubes before. The guys from Manchester  N.H. if I remember. Maube they know what it is. Dave the Boot had a pile of ENI stuff at one time and may also know.

These monsters don't need a socket.  The grid ring bolts directly to the chassis.  Good picture with it's little cousins here...

That poor broadcash variable loading cap must be begging for mercy when that baby is qro

ENI is the former Electronic Navigations company from Rochester (?), which made a line of broadband class A amplifiers for many years for industries, mostly MF up to UHF. They are gone now, bought out by MKS of Colorado. ENI quit making the wide variety of amplifiers once MKS acquired them - their technology was quite dated, using TO3 bipolars in some big amplifiers. MKS has focused on the plasma/RF sputtering/industrial aspect of RF power at 13.56 MHz and other ISM frequencies (part 18 of FCC R&R). A new company has arrived to make new ENI-like amplifiers, some with the same model numbers, but obviously new componentry. They are E&I.

Cool John,
I bought a pile of ENI stuff at hostraders that used a pair of MRF429s at 13.5 MHz. I replaced the Input/output transformer and got them to cover the hf band. I plan to combine 9 of them someday when I have nothing to do.  fc
