[QUOTE="handsome, post: 1093998, member: 772"] Most "P" equivalent tubes were designed for series usage - the Phillips datasheet specs PCC88 as suitable for series or parallel heating. At least "P" series tubes we know were manufactured back then and to spec - today's manufactured ECC88s simply could be badly made - were you using modern or ye olde dusty originals in your experiments?
