Philips E80CC 6085 Platinum Matched pair NOS Holland Heerlen plant Styrofoam box

Two pcs (platinum matched pair within 5%) of rare NOS Philips E80CC / 6085. Made in Philips Heerlen plant in 60s, much better sounding than later types, not even to mention Tungsram / Siemens version. They come from original styrofoam packaging 100 pcs. DELTA logo is clearly visible on photos. The same etched codes! They are carefully tested and matched on calibrated Metrix U61B tester with 250V on plates and -6V on grids and they test over 5.0 mA, value for 100% NOS tube is 4.8mA at this voltages! Gold pins, low noise, well balanced sections and carefully matched thanks to big number in stock. If you are looking at this listing, you surely know that this tube could be ultimate sub for ECC82 / E82CC / ECC802S / 12AU7 / 12AU7WA / 5963, as I personally checked in few amps and preamps, but please do not ask me about warranties how they will sound in your devices.
