fair play.... might be worth a bit in "installs" keeping local pubs/bars/civic halls happy.

Well the T03 should be worth something as worst case scenario.

Jbl man I think you're on the right track.
As I remember it Metro Audio was one of C-Audios brands, they obviously built amps, but were also manufacturing talkback systems and even distributing smoke fluid! Going by the four mounting bolts on the front panel, I'd say they were the same model (CA4?) that was used for the original Avitec Beta 800 and Rauch Powerblock 44, Big laminated transformer with 4 pairs of To3 Hitachi FETs per channel, must be nearly thirty years old, after a cleanout and a recap they'd probably be good for another thirty. |

Yup,i thought the graphics and layout of the front panel resembled the early Avitec Beta's. Probually good solid amps if that is the case. (C-Audio built?)
But clearly not a V800 or HH at all. |

Hmm, I crewed on a tour in the mid eighties with an Entec supplied Martin RS1200 system that was powered by racks of powerblock 44's.
A couple of weeks later I was shown the new range of amplifiers that Avitec were having manufactured for them, I couldn't help to notice the (identical) back panels and similar front panels. I've seen the inside of plenty of the Avitec amps, but never saw the inside of the Rauch amps and assumed that they had the same internals. SMP have you got any pictures of the PB44 internals, to compare the similarities / differences, maybe your amps are newer models than the ones I remember lugging around all those years ago. |

I can post some but they are out doing what they should at present (earning rental) but one is a floater/spare that will return lwhen it is swapped out for the amp it replaced temporarily
So will take some incidentally they use a "Heat Exchanger called a "Pinfin" the only thing Phil Rimmer/Pantechnic did get right still basically the "Hitachi" Topology just uses a "Flatpak" called "HPAK" Hitachi 2SJ50 2SK135 Die in a different package. Apparently quite a rare find and sell for over £40 each as a spare I have a 100 or so here nice new ones since 85 as well a a few boxes of TO3 Hitachi |
