A New Zealand made Holden Wasp made in Christchurch. This is a real monster, 200 watts, four (original? GEC) KT88's and about twice as heavy as the Rockit Super Sustain. The pre-amplifier is is also valve, two ECC83 double triodes, Great sound, far too loud? well maybe not if you are trying to play over hoards of screaming fans, or if you are AC/DC; see here for more about the genesis of Holden Amps https://www.audioculture.co.nz/scenes/new-zealand-made-guitar-amps
This needed a good amount of work to bring it to life, it has been repaired not restored, I will do more to it but don't like to change the original "character". It was disassembled cleaned, including switches, jacks and valve sockets, bad solder joints remade, some small capacitors replaced....it was a while ago a few years and so no internal photos... yet. The vinyl is in reasonable condition considering the age and so I wont be replacing it. Nice touches include gold piping on the front lower cabinet and a stylish grill cloth also in pretty good condition.
Sound: phenomenal, a little noise but not a real issue, but again warm and rich. It's too loud to test distortion when over driven, I have no speakers I could use that would take it! Also I keep in mind that the valves are probably as old as the amp and there's still a little more work to do to make it "like new".
N.B. This amplifier was one of a few that I have seen that had the safety earth wire disconnected; I tested and found no earth, opened the plug and saw it had been removed, cut off short, after rewiring the plug still no earth, it had also been disconnected at the amplifier, cut off and tied. This is insanity. The safety earth should never be disconnected on anything that was designed to have one. On an amp of this age that has not been fully reconditioned I would also use a residual current device. (but don't rely only on that, it must still have the safety earth)
