Happened to catch this video yesterday. I guess the backline for all bands playing Beat Club was Orange Matamps but I think Kossoff may have used them on other occasions as well. The sound was pretty good. Any other Orange Matamp fans here?
Was the ORS the link between the Orange Matamps and the OR line. I remember an ORS on eBay back when I was still collecting amps. That was the one that got away from me as I have Orange Matamps and OR amps. If I were younger and not past my amp collecting days I might want to talk to you about your ORS.I’m in the U.K. I actually have one of the ORSTs left to sell. They are interesting beasts as they have a wide range of tones and are capable of much more grind and dirt than my OR120s.
Yes both cabs have Greenback G12H30s
Appreciate that info. For some reason I thought there was an ORS model that after Cliff Cooper stopped selling the Orange Matamp line. It was quite a while ago that I thought there was an Orange amp on eBay advertised as an ORS100. It had the look of the pics only OR120s that Cliff Cooper sold. I could be misremembering though.The ORST was the first Orange/Matamp. It succeeded the Matamp 2000. The designs are quite similar with Boost, Drive and Depth switches, built on RS tag boards. The components on the Beat Club amp (serial no 49) and my own slightly earlier one (serial 28) all date to 1968. They both use Pennine transformers. The first 100w are OR100 and are on pcbs, the parts date to '69 and on, they use Partridge transformers. I've worked on a couple of 50 (or 70w depending on what you read) that are on the same pcb as the 100w amps but with similar switching to the earlier ORST and Partridge transformers. Later came the GRO series that lost the depth and drive switches and gained the FAC switch instead, the placement of the FAC changes with the different iterations of GRO and the first OR120s over the early 70s, not forgetting the varaint with the mid lift inductor similar to the Matamp GT120 etc.

Here is my clone (sorry need better pic):

I'd forgot about the GRO. IIRC they looked identical to the pics only OR amps but there was some kind of difference between the two. Do you know what it was?you might be right. I am far from an expert on these, I can only really quote from my direct experience of servicing and repairing these (mainly OR100, ORST, pics only 120s and later 120s). I not had my hands on a GRO or any of the oddities. Orange/Matamp timelines are not very well documented due to the schism in the early 70s with parallel production for a while.
Yes, thanks for posting that I remember that thread. I tried to summarise it succinctly in my post above! The Orange forum is a bit slow and technical discussion pretty sterile. I’m still on there but rarely.I found this on the Orange forum regarding the differences between the ORS, GRO and OR models.
