Goldentone Guitar Amps - Old OZ amps

Postby chrisp » Sat Feb 03, 2018 1:24 pm

I'm in the process of stripping down a friend's Rose Music Goldentone 1960's valve amp (2 channel, normal and tremolo) to see if I can track down a signal fault. For those unfamiliar these were Ozzie designed and built, usually point to point wired, valve amps. This one has a lovely Rola 12" AlNiCo for its speaker.

What I didn't know is that the tubes used in this thing (a pair of 12AX7s and a pair of 6GW8s) were also Australian made - a brand called Miniwatt. Apparently there were up there with Phillips and AWA as quality tubes. The 6GW8 was originally I believe designed as a TV signal amp tube, but adapted by a few Aussie amp designers for guitar amp use.

I really hope I can track this fault down 'cause I'd love to get this beast warmed up (yes, I do know about power and capacitor issues with old amps that have sat unused for a while) and give it a burl. But I am also lamenting the demise of Australian electronics manufacturing - we don't make valves here anymore, do we? ... and I know of perhaps one audio transformer manufacturer, out at Hornsby.

It's well worth getting that amp going Chris. There is a company here in Melbourne making hand wound transfirmers for audio. They are currently re building their website but it's worth a look.

The Classic Australian Valve Amps page has a whole section on Goldentone,

Unfortunately, the originator of the page, Roly Roper, has passed away, but the enthusiasts from AGGH still maintain the page. It has details of the various models, including photos and schematic diagrams.

Well worth a visit.
