- RADIOHF - FS Drake B Line
- $800 plus shipping
Very Good condition Drake B Line. Recently back from a Drake Tech where it was fully checked and aligned to factory spec. Capacitors and out of spec parts replaced, switches deoxd and lubed etc. Cosmetic condition is very good with very few blemishes on the cabinets. Fully operational and ready for a new owner to use.
Includes all that is shown in the pictures.
My preference would be for pickup but if shipping is desired it will be at the risk and expense of the buyer. I would properly pack in 3 - 4 boxes with packing to prevent damage but with older tube gear, there is always a risk of damage from shipping. The buyer can use their own shipping company, or I have an account with Pirate Ship, which usually offers low USPS and UPS rates.
Cash, Zelle, Check, or Money Order, and all sales are final. Video of it in operation last night.
