  Just flip it over and look on the volume knob side of the amp in one of the peep holes with a flashlight towards the side of the amp like picture .Mine is a 2012 model and it has a revision 2.0 board   if its more recent i think its a revision 4.0                                                                                                                              


The searching took a while, but I found it: 4.0!

 Thx!
 
Still, for accessing the switches if I want to try different sorts of tubes in a possible future, I think it's easier to open it up, right?

I dont recommend opening it up its a pain the only thing you need to get is long jumpers and its going to be a breeze to change them to try other tubes

  I would like to know what all power tubes are direct fit and swap. for the ld mk iii
 
Thanks

 
I recommend to try the 6N6P-IR or 5687 with the respective adapters from ebay! Don't bother with any other ones, seriously.
The only other othe alternative would be the 6N30P-DR but the prices are sky high.

Yea. As of now have two IRs a pair of 6N6P-i and 6N6P.

I might experiment with diff drivers now. I have the voskhods and mullard ef92 by now

 
Nice one. The 5687s are actually amazing, once you can convince yourself to spend $40-50 for the pair with adapters. I have tried not many different ones, but the Tung Sols are very nice. I heard the GE 5 Star should be great as well.
 
The next driver tubes I would suggest are Tung Sol 6485 and Ei 6HM5 tall bottle.

I guess no more power tubes. And tung sol or the sylvenias could be the next buy.

What are your thoughts on connecting the pre-outs to another headphone amplifier (Solid state) so it drives headphones like low impedance cans.  Basically making it like a hybrid.

I prefer the idea of adding an outboard output transformer (I believe some Grado fans have done something like this).

As long as you dont use it as preamp with vintage  DC coupled amps

I have just ordered a set of the adapters from HK, and am about to buy a pair of NOS Sylvania (US-made) 5687WA for GBP 15 each.

Are they any good, or would NOS 1969 Raytheons (JAN, long black plate version) be better?

I will be using them with the Voskhod drivers (and DT250-250s).

The weakest point on my Mk III appears to be the volume pot, which is a cheap, scrapy affair with poor channel balance at low volumes. How easy is it to replace this (and what would be the best replacement - would an ALPS Blue fit in the case?)?

Also, has anyone successfully upgraded the input and output caps?
