Marco's journey to Tannoy-land

[ff1d1l]

Hi Any chance of photo's?

Vinnie

Some pics


The Lenco in slate plinth and the St 20 below, the Leak has had modern binding posts fitted and an alps pot, also wondercaps and nos telefunken output valves. The lenco was modded along the lines of the audiogon thread - resin reinforcement of top plate, replace springs with elastic, deaden idler wheel and arm with ptfe tape, rebuild and lube motor, clean and relube main bearing (and others!). I had a lingo & cirkus Linn with a Naim aro on prior to my Lenco adventure - same cartridge. I'd say this set up is an order of magnitude better, maybe 30 to 50 percent improvement. And the bass definition is of a quality the Linn never even hinted at.







The curse of the mummy effect on the arm is ptfe tape - notable reduction of strain and increase in clarity on loud passages makes this a top tip worthy of the pages of Viz.





Speakers are birch ply, extensively braced between inner walls then with plaster cast inside to give non parallel surfaces. Rapping the cabinet confirms they are VERY dead. Cheap Argos duvet for internal wadding. Internal wiring PTFE wrapped silver. Ports are adjustable and I sometimes do. Driver chassis are earthed to house earth and magnet assembly braced from rear of cabinet. Dustcap removed too. These are the 12" monitor golds with butyl surrounds, btw. Crossovers aren't stock gold crossovers with adjustable pots, but are from silver series, and are external, connection with 4 terminal Speakon. Cable to amp is twin and earth mains cable (Twin and earth mains? I'll get my coat....)





Will take some photos of the Autographs and post soon.

That is an incredibly well set up system. It must sound amazing.

Have you checked those original 8uf and 2uf crossover capacitors Nial ?

Given yours seem to be quite early Xovers they are probably oilers however poss might be early lytics ergo prone to going

I haven't - the crossover boxes/tins are sealed and mint, so I'd be loath to open them. But pretty sure silver crossovers capacitors were oil anyway. Occasionally you see them dismembered on ebay or the web, and seem to be oil as far as I can recall.

And Steve...mmm, really doesn't sound too bad at all!

Always the problem with Silver/Red crossover boxes for sure
In the end I used to build my own mostly so I could play around with components ~ The Golds are a breeze in comparison if you are not too cack handed to drill out a couple of rivets , and I would always recommend replacing the Lytics if nothing else !

Well, have several gold crossovers, and they surely don't sound as good as the silvers, so might well give it a whirl. But as well as having paper in oil caps the 12" silvers have no switches either, and are (I believe?cant remember where I got this!) a rather simpler circuit so maybe thats why they are preferable...

But thanks very much for the diagram/pic. Will get to it when I have some time...

Quite true Nial ~ Circuit for your Silver 12" Xovers

[Marco]

Hi guys,

I'll contribute more later, been a bit busy today, but do any of you have detailed pictures of wiring diagrams/circuits for the original Gold crossovers (these would be useful for something I'm doing at the moment) or also any pictures of original Red crossovers, so I can compare them to what I've got in my Lockwoods?

Any help here would be appreciated. Cheers!

Marco.

15" er Red ~

Nice one, Roger, but with Reds I meant actual pictures of crossovers, as per your post #175

Cheers for the link to Golds!

Marco.
