I wish I still had my Linn Sondek setup from the early 80s, that setup could put anything digital to shame.
I had a Mauritian mate in the 80's whose brother owned a Linn Sondek it was awesome we could here it clearly 300 meters away down the street and the clarity too just wow

Yeah I have heard a lot of Linn stuff. For three years back in the 90s I worked for Rogers

http://www.markhennessy.co.uk/rogers/

Making the speakers on that link ^ for the BBC and collectors with lots of cash haha. We used to have all sorts of other stuff there for testing etc.



That was my setup back in around 1998. I had a Rogers E40A valve amp running my mids and highs and a Soundmaster VZ running at 2ohms for about 2000w into a Cerwin Vega Stroker 18" in a B36 Intense! cabinet.

The amp (better pics)





That was an expensive amp. About *cough* six *cough* grand IIRC. It was one of my parting gifts when the place closed down and moved to Japan. The Japs always had a really keen interest in british audio gear, so buying Rogers was high on their list of priorities. TBH I think some billionaire just decided he wanted to buy the LS35A cheaper so bought the factory lmao.

BTW guys already hawking my next project..

See this?

Well look at the price. Then add a little soy sauce and....

Update. So I have been humming and harring about what to do with the shell. It's quite odd as it goes together like a jigsaw puzzle. If I plastic welded it (the mid section) then I would never be able to get it off to put a finish on it. You can't plastic weld painted edges, so I had to come up with a plan. I plastic welded the front to the two sides in the end, and the back still slots in. This brought its own problems though, I had to basically cover the front and two sides as one piece after sanding any sticking out edges smooth.

The back is its own entity and I decided to go with brushed black for the front, back and sides (so the mid section).

I am waiting on glue so that I can put the veneer on the top. I have a few small parts to paint black too, so I will get those all lined up to be done together.

The top and bottom each have four bolt holes that go into brass posts. They are like motherboard posts, but they are M3. So I have ordered 10 gold bolts from China (£2.80 for 10)



And of course it needs some feet, because when you put the bolts in it then sits on them and I don't want it scratching my desk.



They are very small and perfect for the project. I was going for the art deco look any way, and there are Georgian influences in art deco.

I will get some pics of the shell progress tomorrow

OK so here is where I am at. Firstly I have covered the sides and the back, and also veneered the top with the walnut burr.



As you can see, the feet are in. Very happy with the walnut, now I gotta hit it with a ton of clear.

OK been working on this every other day for the past while.. It's been a test of patience tbh. The veneer was full of pin sized holes (you can't really see it unless you shine light through it) and the clear was producing bubbles when painted on. So I have had to give it about seven coats and do some sanding. Problem is the surface of the veneer is not straight it's very bumpy and wavy, so it caused flat spots in the clear. It's not perfect but I am happy enough with it. It will have a decal etc on any way, so the worst will not be visible.

Today I painted the inner valve holes black. Still got to paint the outer edge black.



Won't go into the final design, but it's a bit complicated and will take me a few days yet at least. The gold bolts have not arrived yet, so I could not assemble it any way.

Ahh, the beauty of side quests eh? I bet you all thought I'd given up on this.. I actually put about another five man hours into it but did not take any pics. Any way, the top was lacquered and sanded back about five times. The burr is full of tiny pin holes, and they each spit out a bubble when you start the lacquering process. As such it required a shed load of work, just for a small piece ! but detail is king.

Any way, months ago I ordered some gold leaf sheet with adhesive back. It is kinda like vinyl, but it's stiffer and more brittle. Here is what I got.



That is just the top. I also did a lot of edge painting/feathering today also for the other parts. All that is left to do now is wait for the two coats of lacquer to fully harden, then cover the inside of the top with gold, then assemble.

But yeah, it's still in progress

There's just something incredibly captivating about valves. I've been hooked since I was about 14. I was given an old stereo/gramophone thing and it was toast, all apart from the amplifier unit. I rescued that, re-soldered and cleaned it all up and then used it with my record deck for years (it was phono stage only)

That's how most boutique builders who sell their amps for £2000 started; tinkering with old radios and stuff.

It sounds and feels so much better. Digital and solid state technology has improved enormously over the years—to the point where professional touring musicians are willing to let go of their 30kg 50-year-old Marshall valve heads in favour of the convenient lunchbox modelling device—but the way the harmonics of an instrument works with vacuum tube amps, that's what makes them so desirable. Some call it snobbery and unicorn urine, but that's complete BS in my opinion. While I can't tell the difference between a £2000 digital amp modelling a £2000 tube amp in a heavily compressed YouTube demo, I can tell the difference in real life, where it actually matters. The way the amp reacts with your playing is where it counts. An audience of a few thousand wouldn't be able to tell the difference, but you the musician would.
