Holy high voltage!!! $7k for an AL1500 with an 8877?! I have an AL1200 that I
got cheap several years ago.
It needed some work and in the process I installed Ameritron’s QSK-5 PIN diode QSK switch.
The AL1200 isn’t as easy to drive as the 1500, so I changed a primary tap, added more filter
capacitors to the string and so increased B+ to about 4 kV no-load. A few other changes followed
but nothing crazy. It’s much easier to drive, now. Overall I guess I have less than $2k in
it. But even that amp is now $6k!!
The last time I paid attention, the AL1200 was about $4k and the AL1500 was a bit less
depending on the tube. But I haven’t been monitoring the pricing. When did they
get so expensive?
Since inflation is now 12%+ and the cost of labor is through the roof.
Blame the appropriate political party in charge at the moment..
