Jim, this is for you!
A shot of the 5 valves which control the MM stage, the tape/in out, aux and also L+R channel out to power amp.
A few mods. We have Yannis Tome intrinsic wiring to the MM stage and the L+R output channels. Finally silver WBT RCA;s. The far right valves (last two) are the Mullard 6SL7GT which I re-installed. All the other goodies are elsewhere in the amp!

These have just come out of the pre-amp RCA 6SL7GT not sure of the vintage. Some notes coming up at some point.

Enjoy.
Hi Andy,
Those other valves in your amp with black bases (not the Mullards) are fairly generic Russian valves, which are ok, but nothing special. You can do considerably better! What you need are these boys, proper 6H8C (the 6H9C you need look identical), made in the Melz factory during the 1950s:

The thing to look out for are the distinctive holes in the anodes... Those are stunning sounding valves, with really airy highs and superb dynamics.
Also, the Mullards you're using are also fairly generic, and I suspect simply re-badged Sylvanias. What you need are these, 1950s 'Tall Boy' brown short-bases:

Themz PROPA! And a totally different ball game to what you're using.
Trust me, if you can find what I've recommended above, and fit them in your amp, you'll be blown away by what you hear! :)

Marco,
The left three valves are all non-military spec Reflektor valves which came with the amp. The other two could well be re-badged Sylvania's but they sound so different and better to the two which I've just removed. I have a two types of Melz coming from our Russian friends and for the price I'm not complaining. I'm probably going to get a lot of enjoyment trying the Russian valves and it works out cheaper than a night on the tiles (but without the hangover)! I'm working on sourcing a pair of Mullard brown bases and also a pair of Brimar 6SL7GT's! All good fun. Just out of interest, I have a question for you regarding the left three valves. The far left valve is for the MM stage (which I don't use), have you any idea which of the remaining two controls the AUX RCA input? I'm thinking on experimenting with this valve as I think I can get more from the pre-amp this way .
It's much more likely that the first two valves are for the MM, the same as Croft amp using the smaller 9 pin valves.
The third could well be a cathode follower also associated with the MM input, I haven't had direct contact with this type of pre.
To prove it you could take out these two (3) valves and see if the Aux still functions.
PT III - Valve madness
OK, The Melz have arrived and I have now just purchased these badboys
I managed to find one of these for £13!!!! Now just need to find another. I'm in no rush.

I also have a single Brimar 6SL7GT on its ways. So it looks like the Melz going in this weekend.
Stay tuned
