Am testat acest amplificator cu tubul Gu81 la maxim iar acesta ma suportat.Recomand in QRO ca o piesa serioasa si foarte utila.

An Eimac/Econco rebuilt power grid tetrode, a 4CX20000A, previously installed in a Harris HT20CD commercial FM radio broadcast transmitter for KTIJ-FM, exhibits a metallic clanking sound when inverted. Suspect internal damage to one or more of the vacuum tube elements.
