# VAC Renaissance 70-70 300B PPP Dual Mono Amp – Buyer Notes
Is £5,000 the right entry point for a used VAC dual-mono 300B design? Against your own comparable dataset—median £6,314, interquartile range £4,124 to £7,897—this asking sits comfortably below the 25th percentile, suggesting either genuine motivation to move it or a pricing error. The VAC Renaissance 70-70 commands respect in the market; comparable used examples typically trade between £5,500 and £7,000 GBP. At £5,000 in good condition, you're looking at a legitimate under-market opportunity, though verify the seller's rationale for the discount.
Before committing, confirm the output tubes are original or recently replaced—300B rollers are expensive and can indicate service history gaps. Ask whether the unit has been recapped in the last decade (VAC's power supplies benefit from refresh around year 10–12). Verify the seller can demonstrate stable operation across both channels and that all original documentation or a service log is included. A unit of this caliber should come with a recent power-on test, ideally from a tech familiar with VAC's topology.
