Timely service, Good performance.  Time owned: 0 to 3 months
I was rebuilding a Swan Mark II amp and needed tubes. Had read of good luck given by folks and turned in a on-line order. Received a email confirmation; I originally just wanted 2 tubes for the order. About 10 days later, I emailed to find out the status of order; they were not available to ship, but Carey in tube sales asked if it would be ok to substitute a matched pair for $8 more, if they came in first. Told them that's fine with me if they came in first; got a email correction of order to reflect change in tube order. 3 weeks after order placement, tubes arrived, tubes in molded foam packing in a tight box. No damage, each tube had a 2500 plate voltage performance sheet showing plate current at 0 grid voltage; each tube showed 115 ma plate current. I let them bake in, minus HV for 24 hours then checked performance first at 1900 volts with 600 watts for 50 watts drive. 3KV gave about 1100 watts key-down with 50 watts in. Very impressed and satisfied with service and performance of the RF Concepts tubes.
