Default Toob Amplified PC Speakers

It's winter, and the amplifier in my PC speakers just died.

I think it'd be kinda cool to have a toob speaker amp, but I'm too lazy
(and time-challenged) to build one up from scratch.

Are there, by any chance, kits out there? I'm not looking for nickel-
cored transformers with solid silver windings, genuine paper caps rolled
on the thighs of virgins, toobs dipped in LN2, and all that crap: I'm
just looking for something that'll give the audio quality of a mid-range
amplified speaker set, in a cabinet that shows off the fact that it all
uses ancient technology to get the job done.

Suggestions welcome.

TIA


This kit has been around forever and seems to get good reviews:

There's also this little kit from a Chinese seller on Ebay:

which has the output transformers on board - you'd need to supply a
power transformer.

You'd have to put them in a chassis if you wanted it, but since they're
both mounted on PCBs it shouldn't be too hard: buy an aluminum chassis
and punch holes for the tubes, mount the board underneath so the tubes
poke through and then mount the transformers underneath or on top as
your preference.
