As you may know, RF Concepts recently released the new Alpha 9500. It uses a single 3CX1500A7 / 8877 tube to achieve 100% duty cycle legal limit[FONT=Arial, Helvetica, sans-serif][/FONT]. It also features an RS232 and USB port for remote control. Priced at $7950, it's RFConcepts' flagship product. Here are a few close up pics of the inside of the new amp.

I have a few pics of some of the other boards. If there is any interest, I"ll post those, as well.

It looks nice!
 

Hmmmmmm........ no knobs? I don't care for it. I like knobs on tuned amplifiers. Push buttons are for antenna switches. :thumbdown:

Apparently it's their idiot proofing method, not calling you one but some newby hams are and they get to play with big toys by right of licensing and not by IQ.
 
It's also justification for the price tag. I don't know, I just prefer manual tuners, except mobile, and manually tuned amps. Less to go wrong. It would suck big time to have a stepper motor drive chip fail during a big contest and have all the guy's running cheap little Ameritron AL-811's walking all over you and your busted Alpha. :biggrin:

    Hello gentlemen and Ladies. I have the dreaded RCI-2990 receive issue where my radio gets distorted when people get close to my location. I found the C90 Capacitor, but I can not for the life of me find the C89 capacitor. Can or does anyone have a picture of the exact location of C89 ? Thank you in advance, Wes
