    Description

    For sale are adapters to plug 7027 / 7027A tubes in 6L6GC or EL34 amps.
    7027s have the lower heater current of 6L6GC, same bias voltages as 6L6 and post 1990 EL34s*, higher power of EL34, but have
    redundant pins 1 & 6 that aren't on 6L6 or modern EL34s.
    (very old EL34s from far before 1990s i.e. the british mullards with holes drilled in guide pin had an extra pin 1 electrode; this adapter will make 7027s equal to EL34/6CA7 from last 30+ years but lower heater current than EL34.
