Been watching all the frontman25r s and other cheap little fenders go for a song on trade me and it occurred to me that one could use the combo cab for a nice tube amp build. Maybe even the chassis once it's gutted.
Anyone done this ?

For example, here's two that would be excellent for a champ build.

What is?

only once, the cab was to narrow for the tube amp chassis.

thought about it, I think the general problem you'll run into is the chassis' are built for tiny SS transformers, tube transformers are generally a lot bulkier. Having said that clever layout design and a bit of ingenuity you should be able to fit a fairly simple SE 2 tube circuit in a 10Watt SS amp pretty easily.

I actually have an old Kustom 100Watt Digital Head that I'm gonna rip apart one day and turn into a Supro style Head

Great Scott! Better than new

I think this is practical. I have a Marshall valvestate combo that now houses a cool vintage Princeton circuit. It fits easily, though I needed to do a bit of regluing of the cab where it had begun to separate: old combo boxes take a battering.

Got another one on the go at the moment. Used to be a Behringer Thundershitbird until last week.

Looking good! What is that, a champ?
