 For Sale: 2X813 amp  
Homebrew 10-80 meter amp with two 813 tubes, tuned input, continuous output tuning (roller inductor), Peter Dahl transformer, and rack mount. Output is 500-700 watts depending on band and will do more but that is about where I ran it. I plan to be at the Lawrenceville, Ga hamfest boneyard in a couple of weeks. If you are interested, drop me an email and will send more pictures. $400 and if you pick it up in Birmingham, I'll include a full-size rack on wheels.

 AMERITRON 606 AMP  
PICK-UP Only or if you want it shipped I will take it to UPS and have it professionally boxed and shipped but you will have to pay for that. I am asking only $900 for a $2500 Amp which I guarantee has less than 50 hours as I find that my VQA HEX and 200 W Radio is all I need and when I did run it....never over 800 Amps! So if you are in the Las Cruces or El Paso, a short trip but open to anyone who wants to make the drive. This Amp is in EXC Condition! Another reason for selling is that I am 77...78 in February and am told I can't take it with me! And 1st come 1st served. Please do not try to bid it up because my price is firm.

 WTB Yaesu RDA-30 300PF Doorknob Cap  
I am looking for a RDA-30 300PF Doorknob Capacitor. This is from a Yaesu 2100B. It is the skinny disc type, which it has to be so it will fit in the amplifier. The amp has a few other of the same type doorknob caps that could be changed but they still work atm. The 300PF one definitely is bad as it has cracked into pieces over time. If you have one I would be very thankful to purchase it from you. If you have others and you are willing to part with them I will buy them too. It looks just like the one in the picture but 300pf. Thank You , Blayne N8ZJ
