Wonks, that is super useful. Thanks so much for that info. I'll see if I can get some pics of behind the panel.

Now that you have told us you need the ministrations of an amp tech' you could be in for an expensive time? Just safety testing and, if it passes, running the amp up is going to take a couple of hours of a tech's time and if it is safe but faulty almost impossible to give an estimate for repair. Just a set of output valves will be £120 I would think.

I actually bought it to use it. I managed to pick it up pretty cheap at £180 and although it seemed to be working fine when I collected it, as you've noted I think it had been sat unused and unserviced for some time so it's prudent to get someone to give it the once over just to make sure it's safe.

Well that's another new name I've learned today - thanks Wonks! :thumbup:

On further investigation, "Traffolyte is a generic name for pnenolic engraving laminate. The material is made up of three layers, the outer layers being engraved to expose the contrasting core. It is available in two thicknesses – 1.6mm or 3.2mm"

https://www.traffolytelabels.co.uk/traffolyte-labels/

Aha! Now I recognise them - I've got a 'beware of the dog' sign attached to my front gate that uses this material. Never heard the name Traffolyte before though.

Damn! Got the spelling wrong. Still pretty much the go-to material for engraving labels for control panels and MCCs in my line of business.

I acquired a few dozen sheets of it when a local place closed down, passed most on to a luthier mate but hung onto a few........

I am still intrigued as to what for! Ok, a bit impertinent, you can of course do WTF you like with the amp but a few words of caution?
If you are just going to use it as a clean amp, maybe with a pedal or three affront it fine, but it will still need 200 watts worth of speaker attached. If you intend to give it the absolute beans, 300 watts would IMHO be the minimum speaker load rating. Those are Celestion driver ratings, e.g. 4X V30, other speaker makers are far more "optimistic" with their power ratings.

Aha - I've been slow on this one, but just realised that by chamfering the edges of Traffolyte this material is what gets used to create those 'purfling-like' edges on various guitar scratchplates?

Similar. Scratchplate/pickguard material is normally a bit softer. Traffolyte is quite hard and brittle, so not great for scratchplates not firmly attached to a flat surface.

Was it invented by a Mr or Mrs Traff like Bakerlite? I shall have a Googe.

I think it was named after the original Metropolitan Vickers factory located in Trafford Park but that might be coincidence.

It did/does contain phonelic dust, depending on brand/age so use proper PPE if you do work with it.

back when I was a REALLY NOISY bass player I bought an Orange Graphic 120 - in about 1972/3-ish, same time as I bought a Rickenbacker 4001 stereo bass. I also somehow got in touch with whoever was Orange at the time & managed to get involved in one of their weirder cabinet designs. Two 15" speakers in a sealed box, one facing up & one facing down, with an outer rectangular box which had parabolic reflectors built in top & bottom. I fitted mine with a pair of 150 watt Altec Lansing speakers that I got from the then UK distributors for a song. Super efficient speakers and the throw from this cab was enough that I once used it at the Hammersmith Odeon back in the days when PAs were not man enough to take a DI`d bass!!
My amp was a classic Orange beast, really solid chromed chassis with rails that meant you could slap the amp down on a bench with no fear of crunching the interior components. Wiring was a work of art - well up to HiWatt standards. The only downside was that they had over egged the treble control. Would go into parasitic distortion really high up if you went much past midnight on the treble control. But bloody hell if you wanted a really loud clean bass sound with just enough valve yumminess to put a smile on yer face this was IT. I would love to know what happened to that speaker cabinet.... cant even find a photo of one on the net, but the one I got was a prototype AFAIK, so maybe mine was a one off. Aha!!! googled again and found a photo of one!
The chaps on Talkbass didnt seem to know too much about it but it DID make it into production!! Here ya go: https://www.talkbass.com/threads/replac ... ge.720773/

Bit sad. Apparently I am a zombie with the implied meaning that I know nothing from some smartarse at Genz-Benz (thought they had gone under ages ago?) so apologies to anyone that actually clicks on tha tlink.

Following at the link, the Zombie reference was because you had revived a thread from 2013 (which in turn had already been revived from 2010).

As to the cab. I've not owned that particular model but it did remind me of gigging a reflex cab (with possibly a single 15" or even 18" speaker?) back in the early 80's. Probably driven by some woefully under powered HH head.

I had some fun carting that around the Working Men's clubs of the North of England. Happy days.

To be fair, it may be that Andy was exasperated by a first post with a duplicate on another forum. In general, it's poor etiquette, as people can waste time answering questions that have already been answered elsewhere.

But welcome to the forum triscon2, and I'm glad the resident gear junkies have been able to shed some light on it... :thumbup:

Just think what would happen if the internet had been around in Anglo Saxon times?
