Two tube amps for your consideration please

Old... dog

Can you see well enough to solder? There are kits that have a big folowing which could elevate your means.

Just exposing alternatives here as I suspect adding an amp under $400 isn't a big step up for your system as it satnds... but a DIY one for that amount or not much more might well be as their is a good amount of the preice in amps devoted to the labor aspect...

I saw some recently and felt for the $$$ they were a great idea to those who want to make their own, or simply are fixed by their means.

Then too is the thought of moving up later on and then waht to do with the inexpensive amp bought now? recouing it's cost could be problematic.

Again just thinking aloud.

Luck...

I just did a Google search for “DIY audio amplifiers”, Did some other’s as well but most of these links appeared in the first search.

There was or is a maker of finish it or built up as much as you wish that was popular and presented a great value … although I can no longer recall the whole name… I believe it began with “Van…” as in German, Swiss, austrian, etc. They are a USA enterprise though.

Sorry I can’t be of more help.

So try these if you aim to get the most out of your investment budget…. Or wait a while longer, save some more and do better then.
