Hot caps

[FauDrei]

This X-Can modding thing is getting under skin... (and probably in short term saved my life - been seriously inclined to get one of these

before trying the first mod on my V2)... "Boys" have to do something...

For the time being, I am learning the skills of not burning anything important with a solder iron. The positives so far are that my X-Can V2 is still working and my wife decided to stay for a while longer, at least until I really bring that black beauty home (Ever tried to go out with TWO beautiful ladies? Well, eventually they stop being ladies and it gets ugly).

OK, so I've done the mods "in the opposite direction", meaning that my last mod was to up the PS electrolytics in V2. I reckon it was wrong direction because the PS caps emphasized all the goodies of the previous mods I submerged my V2 to. If diodes added clarity with new PS caps it is clarity now. But I might also having a problem with it - the ten Panasonic FM 1500uF 35V (RS Stock No. 526-1806) that I somehow managed to squeeze in are getting hot.

The temperatures were "tested" by opening the V2 enclosure and touching them after longer (12+ hours) of stress testing (near max volume with HD600). My V2 enclosure already have 4x 6mm holes per tube on top and the same number and size of holes in the back of V2.

It is not "so hot that you can not touch them" or hot as the superb Japanese National tubes tend to get, but is pretty near that (will manage to get a temperature probe if it would be necessary), and much more than stock caps.

Is this expected behaviour? Is there a possibility of a fault part/joint/element or have I done something wrong in my soldering enthusiasm?

Please help. Don't want to become wifeless cripple

They shouldn't even get warm let alone "hot" something is definitely wrong. Are you sure you haven't fitted them the wrong way round? If you fit a cap the wrong way round it will get VERY hot and occasionaly may explode...... check that first.

All cap polarities are good.

Could cold joints (my bad soldering) be the cause?

Update...

Resoldered all suspicious points. Testing it outside its cylinder enclosure...

The caps are NOT hot, only those two on the side (previously populated with 1000uF 16V caps) are mildly warm. Other eight of them are more or less room temperature.

The only things hot are the tubes (can not touch hot) and two of four transistor like things on which I have put the heat-sinks (just warm to hot).

So, either I've fixed it by resoldering or the holes in my V2 enclosure are not ventilating well...

BTW are tubes really supposed to be really really hot? What temperatures are 6922 supposed to reach? Is it possible that I am overloading them?

The valves do get hot, yes, as do the transistors.... perfectly normal.
