A Quick Question about Dynaco MK III Capacitors

When building a new Dynaco MK III amp kit, would it be better to go with a new upgraded can capacitor from Dynakit or a capacitor board from Triode? I'm obviously looking for improvements this change could make to sound quality but, and as equally important, improvements to the maintenance and operation of the amp under modern household voltages. Many thanks!

I don't know about a sound improvements comparison, but I went with the cap board on my clones. Used the Triode chassis and added bias test points to the hole where the can cap would go. Worked for me.

I really didn't think there would be a huge sound improvement, just so long as the change wasn't detrimental. The only sound change I might expect (and this is highly subjective) might be an increase in weight or punch with a power supply upgrade. Just to get it out there with this post, I prefer the original Dynaco circuit over the various other boards that are out there. They may sound fine, but I don't consider them Dynaco amps; only amps that happen to use Dynaco transformers and hardware. And I'm not disking them, only expressing my personal preference.
 
The cap board will let you use what are most likely higher quality capacitors. I'd keep values and such close to stock so it doesn't thrash the rectifier tube but it will let you use parts rated for higher temperatures which tend to survive better. Also cheaper to re-cap in the future.

The can cap will do the work, and it fits. As for sound "improvement" i am sceptical.

Mine are total clones. The only thing Dynaco about them is the output iron. They sound wonderful with solid punchy bass and what you'd expect from a modern tube amp in regards to mids and highs. Clear and clean, which is what I was after. Not warm or tubey. Tried to post a pic earlier but was at work. I like it without the can cap personally.
