Why does the 3CX1200A7 Cost more than the 3CX1500A7 (8877) tube Huh And what would be the advantage in using one over the other in a HF Amp???

From Eimac?  I doubt it.

You might be comparing an Eimac 3CX1200A7 to a Chinese 8877...

3CX1200A7 has instant-on like a 3-500Z and has a high grid dissipation rating so it's tolerant of overdrive (although your neighbors won't be).  8877 has more gain and is good up through 400+ MHz, though.

I haven't shopped, but this is a "beats me" one.

Maybe it's because the 8877 is used in a lot of legacy systems for MRIs and such, and the 3CX1200A7 isn't, so they simply manufacture more 8877s.

But I really have no idea!

I'll bet it just reflects their mark-up applied to the price they paid Eimac when they last purchased inventory. Check again in 6 months and it could be the other way around.

The answer is simple..Volume..The 8877 is popular in a lot of medical devices.  The 3cx1200a7 has not found nearly as many uses.  Other factors are cost to build, and the foreign competition.  But the real reason is the volume.

They are correct in that the pricing is about $1200 on the 3CX1200A7 verses the $950 on the 8877. Quantity can be the only answer. The 8877 is used in many applications where the 3CX1200A7 has a short following.

Some friends of mine just visited Eimac and they saw a bunch of little old ladies assembling the 8877's, all by hand. So I guess maybe the little old lady who does the 3CX1200A7 might make more than the 8877 ladies.
