Roost 120W '70s bass head

One of Brian Roost's finest by the looks of it. Some design similarities with Hiwatt and Sound City, and probably Partridge transformers. I've played through one of these and it was very very good.

roost never had partridge transformers, they had some wound to the same specs but they wern't partridge.

I don't like the look of this head though, the badge, front and back panels don't look like there the original ones. I'd wanna see if any big mods have been made to the internals before i paid good money for it.

This one seems to.

And a quotation from Terry Bateman, who worked for Roost, on the Champ electronics site:

The reason I remember this is because Roost used Partridge in the early days and changed to Electro-Voice about the time Sound City did (1975/6..??) - well Sound City were only across the town from Roost and there was a "flow" of parts to and fro between the two factories - ah what great days they were back then. I've also seen Electro-Voice transformers used in the Sterns Mullard 5-10 and 3-3 amplifier kits.
