The only Alpha I own is a 76PA which I rebuilt from a Carribean contest station pile of parts over 20 years ago with bad transformer, tubes, filter caps, and bandswitch. It has been perfect ever since with 3 8874 pulls that
easily does 1800W and I run at 1200W.

Buying a new 9500 or similar is only for those with a lot of disposable income and poor technical skills. Sort of like owning a BMW: they are fine while in warranty but be prepared for sticker shock after that.

I drive a new leased Ford every 2-3 years. For just running around locally (up to 100 miles or so) a 92 Taurus is fine as I can fix whatever it needs.

Right before I sold my 9500, the factory gentleman told me it should come in for factory attention about every three years. I was amazed. Charly

Larry ,

My Alpha 9500 , purchased  new in summer of 2013 works fine and has not
been to the factory for service.

Also have a 87A ,  also purchased new in 1995 , that went to Alpha
factory service in November 2015. Received repaired unit (  receive pin
diodes ) about 1 month later.

No issues with service from Alpha . Done in a reasonable time period and
feel it was thoroughly checked before shipping back to me . BTW ... unit
was returned double boxed which was NOT the way I had shipped it to them. Back in 1995 these units were only single boxed . Glad Alpha double boxed .
Am sure they learned a lot  about shipping over the years .

I’ve been a very satisfied customer since my first Alpha purchase ( 77DX
) in July 1983. I still have that big boy and have instructed my wife to
put it in my casket 😉 when I go SK.

No experience with K0HM.

repair. I would like to get an idea of your experiences with Alpha factory service and also Brad’s service, K0HM. Which is better, turnaround time, price and, in general how satisfied were you with the updates and repairs. Feel free to answer privately but also feel free to answer publically as I am sure others would be interested. I am getting the impression from the
list that Alpha have made improvements recently.  My 9500 continuously
hunts for resonance and the idling plate current is high. Also, the serial
port doesn’t work but the USB port works.
