Hard to find - matched pair very early vintage PCC88 (7DJ8) made by VALVO (Hamburg) as pics. show for sale. Similar to ECC88/E88CC/Cca/6DJ8 types and sought as ideal replacement. Same lot, D-getter, pinched waist - ultra rare! Probably used but in proper condition, tested/matched on Funke tube tester showing readings of 9.5/10 and 10/10 mA (where "good" starts at 6.5 mA). No gas, no shortcuts. From private collection. No return, no warranty.
