Is there a parts list, as so far I have yet to find it in the 40 odd pages I've scrolled through?

Yes, I'll release the parts list when we start taking the PCB orders  wink

Since I just purchased a L75 on Ebay you might as well count me in for a copy.
Thanks!

Hi Joe,

pics of the inside of Chris's controller here - http://www.lencoheaven.net/forum/index.php?topic=5982.270

(looks much better than mine   wink)

Note that the two extra fuses which you can see mounted on the chassis there and which Chris mentions in the text, are now mounted on the PCB.

Someone here asked me about heatsink temperature, so I've done a couple of measurements....

Now, this is measured on my controller built into an old CD player case, which does not use the heatsink specified in the parts list. Rather, it uses one purchased from ebay seller "hifispot168" in Hong Kong. The heatsink is 140 x 81 x 44mm and, although no actual specification is given for the heatsink, it seems to work very well.

So, at an ambient temperature of approx 22oC, The heatsink temperature (measured as close as possible to the mounting point of one of the amplifiers) rises to about 45oC within the first LP side after switching on. After about a further 2 hours of use, it has reached approx 49.5oC.

That's driving a stock Lenco, @ 200V. Repeating the experiment at 240V output makes surprisingly little difference, maybe 0.5oC - 1oC higher. It's difficult to be precise, as the ambient temperature varies a fair bit over the course of a long listening session (Quad II's pouring heat out into the room!  laugh)

Not very scientific, but hopefully that gives an idea. I'll try this again driving my Garrard 301 and see what difference that makes ...

Is there going to be another production run of these PCBs? I'd be very interested in a couple.

Alternatively (forgive the newbie query), could this be done using a breadboard? Is there a guide or schematic available?

Hello everyone!

I am an old member from Lenco lovers. I gave up my restoration when my wife got pregnant. Well, my son is six years old now and I get to restart the restoration!

I would love a set of PCBs for my Lenco. I live in the US and managed to snag two 50hz Lencos stateside. I'm glad there is a workable solution now. So good to see some old names again! Btw, my name is Benjamin. My username is my surname.
