The drill idea would work fine, so long as you know what is behind the trace when the drill goes through.

Since "u duh dude" dat done did the wiring and mounting of the board, you're the best man to know what's behind as that drill goes through Wink

I'd probably use a dremel tool.

Glad I could help, as I really have very little to offer, in the bigger picture! Huh

Hasafraker,

I also have board rev7 2009, and my impression was that pin 6 was unconnected. However my board is installed and I do not have a photograph of the tube-holder side before the holders were installed.

Will check this out today, because I now see that it is possible that my caps are shorted out by the leg of the trace under the tube holders.

UPDATE - GOOD NEWS and BAD NEWS

Well - dug out the multimeter, and it turns out that my CCE caps are indeed shorted out on the tube-side of the board. A pain now to try and cut that trace - but better sound quality to come in the end!

Can somebody please publish a photograph of the tube side of the board showing how these traces run. Steve - could you please indicate which revision of the boards first incorporated the pins 3-6 traces.

yeah I was thinking of a dremel tool with a very small bit to go through from the exposed side of my board.

Alan, if you get it done before me let us know how it goes, I'm going to try to get mine done this weekend, I just need a pack of fine bits. I'll report back when I get mine complete. I'd still like to hear from Steve that there isn't something else in this area I'm going to cut through that I need to worry about.

Sitting looking at the internals right now - got a Dremel not too far away, but I currently have no idea exactly how these traces run on the non-silk-screened side. Obviously, even if I could get the board out, tube holders cannot be removed, and there is little clearance in which to work.

Will let you know what I do - having read this thread, it is not really an option to leave it without the mod!!

UPDATE

Using a dentist's mirror to redirect a strong light behind the board, I can see through the PCB and make out the traces. It runs from 6, across to 3, then out of the tube holder and across to join the other pin 3. Looks to me like the hole should be drilled roughly between the numbers 5 and 6 in order to cut just the 3-6 trace, but leaving pin 3 connected to the trace running out of the tube holder.

Happy to mark out and drill on the basis of the light shining through the board - but I'm not doing ANYTHING till all this is confirmed.

Agreed, Steve please could you confirm a "best practice" location to cut the trace, would be much appreciated.

Well, my impatience again, I reread the stuff, then went ahead and did it. Attached photo shows the hole (same for other tube) - I had to extend each hole slightly towards the 4 before the trace was finally gone, and confirmed that the two pin 3s were still connected, but each 3 and 6 were broken.

BTW the PCB is very easy to drill with a Dremel. I put very little pressure on because I was afraid I might lift the traces. You can see the tube holder through the hole (and yes I must clean up these solder joints  - and one seems to have cracked!?).

And it worked. And - first listen, it definitely sounds different! Will have to work through a few tracks before I can say how much - but at least I now have a before - after.

cool, I salute you and your impatience! Cheesy  hehe. This is a good excuse to grab a dremmel however I think I actually have one, it looks very similar to a dremmel, we got it for trimming our dogs nails... it was expensive which is code for "they will be terrified of it!" so it is just waiting for me to appropriate it to my tool box hehe as long as the chuck will accept standard bits and such, it's a done deal.

Go for it! Gave me a fright though - the sound after the mod was very detailed a bit "brittle" with a noticable restricted sounstage. Fortunately these effects settled after about 20 mins (what is it with ruddy capacitors?!?) ... and then ...

Bach, Brahms, Capercaille, Deacon Blue, K D Lang, Cake, King Crimson, Tchaikovsky, Deep Purple, Massive Attack, Paul Simon, Calexico, Elvis Costello, Zero 7, ... etc etc

Wow! "Gentlemen, this is no humbug!"

I unboxed my old SE34I-1 last week after having Steve do the
Mod,  & there is  a very noticable improvement in clarity,  with
more transparency,  also soundstage depth seems to extend back
farther than before.   sounding really good with an amperex
6dj8 in the preamp section,  russian 6n1p drivers,  & a quad of Ruby
EL34BSTR 's in parallel.

Going to change over to 2 tubes in triode & give Her a listen.

Thanks Steve!

I don`t think I can afford to send mine back, but would love to do the mod myself for the Tori II, what pins do the caps need to go on and what size caps for the Tori II, thanks in advance for the help. Greg

I made the mod to my Torii Mk2 over the weekend --  didn't have the original packaging box, so thought it would take longer to pack it up and send it versus making the mod. Also I didn't want to have the amp damaged in shipment because of my packing.

As per info posted by Zygi and Veryoldcat, I used Xicon .1uF 600V caps soldered  between Pins 1 and 8 for the EL34. Used the 600V caps since some of the cap voltages in the MkII looked higher than 400V -- also because the Xicon caps are smaller they were easier to fit into the amp. I got my caps from Triode Electronics, see :

http://store.triodestore.com/xicpol.html

See posted pic for one side of the amp-- the 'orange' caps are the ones I added, the one in the top part of the pic shows the connections better since the connector to pin 8 is obscured in the lower cap.

hi all
since i have both the se84 and el34i, i modded both amps, starting with the integrated first. --
observed only slight changes for the better with the integrated.
but the mod has lifted the little amp to another level altogether. -- it performs just as those who have done it say.
anyone with the little se84 simply have to get it done.
cheers

All I can say is the audio world is in big trouble, I did the mod this morning on the TORI MKII, what a difference some caps make, best amp on the market.  It drives my Eminent Tech LFTIIIB`s Beautifully.
