Stupid question: What tubes does it take, and how many?

PF, you may want to repost the excellent instructions you already gave me in another thread on how to take it apart; I printed them out for when I am ready to "roll".

Hi Doc,

It takes two valves and you can fit any of the following types: (6922 / E88CC being stock in the V2)

6922
E88CC
PCC88
6N1P
6DJ8
6N23P-EB

I haven't tried the 6N1P or 6DJ8 but they should be OK. All the other types listed I have tried and they work perfectly well.

Blimey Juergen I only put that page together a few hours ago..... you're fast on the button!

why do the X-Cans hide their tubes? i like exposed tubes (also exposed boobs)

 

[mysticaldodo]

From what I understand, the resistors actually run hotter then the tubes themselves in the XCan. The casing is suppose to be an aluminium heatsink but I find better cooling performance with heat sinks installed.

I'm not sure cutting holes in the casing for ventilation is a good idea. Dust might settle in and constant recleaning is needed

I understand other amps with bigger tubes run very hot (like the Cary Headphone amp which I was forced to sit next causing me to sweat

) so it makes sense to expose them and they look nice!

Is there a shopping list with part numbers out there?

You want the following:

6 x 35V 2200uF Panasonic FC
4 x 35V 1000uF Panasonic FC
4 x 63V 100uF Panasonic FC
4 x 16V 470uF Non polar capacitors (Capxon NK 105C series are good)
2 x 0.47 (470nF) 250V Evox / Rifa PHE426 series polypropylene capacitors
2 x 50V 10uF Non polar capacitors (Capxon are good again)

That should notch your V3 up a gear or two. Obviously you can tweak the cap values, none of them are set in stone apart from the 100uF ones (don't change this value), but the above is what I'd recommend and works without any problems.

Have fun.

Mike.

My next plan is cabling upgrade but this must wait as I've bought a car - some maintenance must be done and my wife can't stand the smell of soldering iron

BTW Pink Floyd do you think more capacitance will give any benefit concerning SQ. I mean more than in your upgrade kit.

Is their placement obvious. I mean, do I risk messing anything up?

You could order the kit directly from PinkFloyd and it comes with instruction sheets!

Yeah, I was able to find all but 3 pieces on Digikey. Not worth it IMO, I'd have to wait to order and the brands would have been off. So, I placed order with Mr. Pink today! Now thw wait...

Funny, I thought I offered you better caps for less money?

Oh Well. My Loss
