Did a bit of follow up with various sources and judging by the serials of the Pre and the power amp  it’s from about April/ May  1982. I don’t know if they were still made at Soundwave in Romford by this time….

i also had another stroke of luck , I managed to pick up a later series TE 1 x 15 cab to go with it at a good price (£20) I’m hoping to find a 4 x 10 soon too to complete the rig. Oh and a sack truck to move it about…..

This is what happens when you buy grossly substandard parts from unauthorized (or non-genuine) supply chains. This is not a capacitor issue, it's a fraud issue.

Indeed. Imagine our shock recently when we returned busted Camera boards to  Panasonic UK to be repaired only to find our boards( confirmed by serial number check) contained  fake CAPS in them. Apparently they’d sub contracted out our boards to a third party to service and when they came back the Panasonic caps were not real Panasonic parts…they lasted three months

This is quite simplified, but serves to reinforce why replacing caps in amps just because they are a “few” years old borders on the absurd. Or, the design and selection of components is really awful. 

But let’s not forget the “Crap fake capacitor scandal “ a few years ago. Where copy’s of Nichicon and Elna and Rubycon and Panasonic were flooding the market that caused no end of issues…that hasn’t helped consumer confidence

Hope you get to the bottom of what it is - very cool. 👍

Thank you so much for your input

Leave the caps alone, age does not mean that there are problems, or that there will be problems. The whole notion of “must recap” is an absurd extrapolation from a little bit of truth. 

Yeah in this case i concur that its not necessary but a peek at them to evaluate the state of them would not be completely unwise ( what with it being over 40 years old and of unknown background).

In my day job in Broadcast Engineering we are often replacing CAPS on PSU's in ageing broadcast kit in the transmission that remains on for 24/7 ( SDI routers / vision mixers /Camera channels etc and the like) so it would be a formality to check and replace any problematic ones. We have old kit that hasnt been switched off for 10 years that works fine, but wed be very afraid if it powercycled...

Looks like it could be a MK1 GP11 although I'm not so sure the case is original.. With the first couple of generations of Trace Elliot gear, I believe all woodwork was painted black before the change to the grey 'pimple' type that lasted until the mid / late '90s ie, the early SM and SMX ranges..

 

Hope you have fun with it..

Yeah the case is a definite doozy. its seems  customised completely for this rig.... everything fits perfectly and it looks as though it was made for it.

Truly an enigma. Wrapped in a conundrum.

Ive been enjoying it immensely this afternoon...glorious. 

I would venture it sounds better than my SMX 300 era head and certainly is up with my Series 6 AH500X.

I'm gonna continue my search for info and thank you for your help so far

The sum total of your mojo is some snapped off brittle plastic slider caps.

 

As it sounds great my advice is leave it alone and play through it daily.

I will the usage graph of the lifecycle of this amplifier will be a ruler flat line of inactivity  til this week from its birth ,….to a sudden exponential curve of use and enjoyment I can asssure you!

Through the Di out the GP11 pre sounds very similar through my mixing desk to my old 1008  (8x10 ) combo DI out from 1983. I think it’s wonderful…..

Thanks for your lovely comments.

Dunno. I am a broadcast engineer so of course the first thing I did was open it up to see if anything needed recapping etc and from a peek inside with my trusty LED torch I cannot see anything that has been changed/ fixed / updated or even switched on over the years there’s not dust on the mosfet fins behind the fan, nothing. it’s truly in stellar condition. The only indicator of anything is the snapped off  GEQ controls on the front but that could even be because the plastic has become brittle over the last 45  odd years. I haven’t got the preamp or the power section fully on my bench yet and am a bit trepidant to do so but I may have to in the interests of science! Also I’m gonna try to find replacement faders for the graphic section as that is the ONLY  thing less than optimal at the moment.

Curious and courioiser…..

Just bought this Amp for a complete song. ( Dont ask the final price, you will be appalled …..I gave the guy more than the final eBay listing settled on cos of my remorse for the eBay victory) 

I’m thinking this looks very early (1980-1981?) it has just been serviced & PATested and sounds utterly wonderful.

Any ideas of vintage?

model : AH250G

serial : 2225

model : GP11 Preamp

Serial : 1069

The GP11 preamp is a stand alone unit with its own serial number distinct from the serial number of the AH250G power amp.

Thanks for looking!

Early 2000’s with some real relic / pock marks from playing.

Just had new strings and a setup.

Will consider trade for a PBass type bass or something else. Hit me up there’s no bad suggestions…..

Roland Bolt 60

The same Valve power section design as a Fender Deluxe Reverb 

Has Brand new Power Valves

The Preamp needs attention as it is intermittently cracklly at the moment ( hence the price and parts listing classification)

I guess it needs a service.

I’ve been using it as a pedal platform bypassing the Solid State Preamp straight into the power amp and it that use case it’s given me no hassle. 

Collection only as lord know’s what devastation a courier might wreak!

Let’s hope other folk think so!

What did you buy……?

Lightly used for home practice Trace Elliot ELF amp.

No Issues perfect working Order

No bag etc but comes with mains cable and Speakon to Jack cable.

Sounds fabulous through my GK MBE115 ( upgraded to Faital Pro 15 PR400 also for sale on here) 

Prefer collection but can mail insured for cost.

Lightweight cab (MBE 115) loaded with Faital Pro 15PR400 NEO Driver (800w) 8 ohm this is a single carry load in if you use a small class D amp

This is a considerably upgraded driver which replaced the 200w GK NEO original (the speaker alone was £200 ) last year. It has seen light home use only in this time with my Trace Elliot Elf in a practice capacity. 
 

Another way to look at it is get your Faital pro for half price! And the GK cab is free…..
 

Dimensions 40x50x60cm.

Weight a paltry 15 KG
 

Pickup preferred in South Wales.
