Stuart, I have never seen one of these. Thanks for sharing such a unique piece of equipment. It is always a help to hear you discuss the process of determining the issues of the amps on your bench. Thanks again, Mike

Thanks alot for featuring this amplifier. Always interesting to see these other British amps and their histories. Have a nice day.

gracias profesor un placer escucharlo

I have watched both you and Terry for years and I can tell you he has nothing on you. You are extremely knowledgeable! And in my opinion much more intuitive than Terry could ever be. Moxie is the term that best discribes you IMHO! Love your vids! Thank you Stuart! Steve, 30yr amp tech in California

Hey Stuart, nice little relic and clever fix..! WEM was reasonable brand back in the day, I used to have a copicat made by them...Great fun..Great video..Ed..uk..😄😄

A quick and sweet episode today. I imagine that had the repair been recorded, this episode would have been a two-parter. In the end, it was sussed in your usual manner. I've seen the WEM, but never heard one. I too watch D-Lab. Terry is very knowledgeable. I go cross-eyed while he's fixing one of those ham radios. Well done as always, Stuart. Cheers!

Used to use WEM Westminster 30 watts in the studio back in the 80's. Two mic'd up & then panned left & right, the right side delayed by about 25 to 30 milliseconds through an AMS delay. Absolutely glorious amplifiers.

Great playing Stuart! Cheers from Sicily Lucio

Watkins guitars (Rapiers) amps such as the Westminster, Dominator and their PAs and Copicat tape delays were one the main manufacturers of equipment, especially for bands and players starting out. Good to see this one being kept working.

I had one of these in 1978, it was a birthday present and came with an Avon Rose Morris Les Paul. Together the cost the princely sum of £60.00!!!!

Nice little practice amps, I’ve had a few over the years in fact I think I’ve still got one somewhere. I’m pretty sure that the inclusion of a decent 12 inch speaker made for a decent tone.

Good one Stuart!

I've been caught more than once thinking myself into a circle. I've learned to check the grounds as diligently as the power circuits. Mainly grounds were a problem on the railroad machines I worked on rather than power supply problems, especially with anything using a PLC operating system.

That's a very interesting little amplifier. I've never seen a power tube/phase inverter set up like that. Had not heard of an ECL82 tube until I saw your video.

In many amps the triodes of ECL82 are used in a way that the first triode is s normal gain stage (with a 100k plate resistor etc.) and the second triode is connected as a cathodyne PI. Perhaps because the gain factor of those triodes is a bit low to make a long tail PI out of them.

Hello Stuart. Snap!!! I am just rendering a video for one of these amps I have restored it. I discovered the tubes were biased at 12 watts from the factory. The ECL82s should be biased at 7 watts. I decided to investigate further on why they have biased these amps so hot. Biased at 7 watts the tubes don't match up to the primary on the output transformer. How did the tubes stand it for 50 years. It still had the original tubes in it. The amp couldn't have been used very much. D Lab is a good channel. I think you are a great tech. I have seen you mend some very difficult faults, especially the solid state stuff. Your channel shows all sides of amp repair. Not every channel does that. Take care Stuart.

The silver "WEM" style always reminds me of lab test equipment looks wise

Another British tech I'm subscribed to just posted a WEM Westminster Mk9 repair video literally minutes ago. It's a long Part One, so no playing demo just yet. He's a phenomenal player so part 2 should be even better. See the Vintage Guitar Amp Repair and Online Guitar Teacher channel.

Great sounding little amps .. Well done of finding that very unusual fault.. Besides Terry at D-Lab, Chris at Rift Amps also uses a Boss looper to test his amps.. It gives the listener/viewer complete consistency which is a more scientific way to test stuff in my view. Terry also knows his California red wines as well 😅🍷

the triode sections of both ECL82 valves is used as the phase splitter. The pentode sections of both ECL is the push pull output section. You don't use ECL82 triode sections as power output valves!

Power tubes in series, somewhat rare.

O you got it wrong ecl82 is a triode pentode output is push pull with two pentode one from each valve the two triode phase Inverter😊Ps Ecl 86 more powerful than EL84

Hi Stuart, Can I ask a question as I'm a little confused and please excuse my lack of knowledge , and if it's a silly question I apologise. But, when you were talking about the power supply , the AC comes in get rectified to + /- 220 v DC , then goes through the 3 x 50 micro farad capacitors. I thought that capacitors blocked DC and only let AC through, this is where I'm confused. I wonder if you'd be so kind as to tall me through this, please. I have obviously got my metaphorical wires crossed at some stage and have bamboozled myself. Love your videos, and always look forward to seeing the new ones. Best regards.
