Kit Amps like this beauty from TAD offer the best way to get an unaffordable amp into your hands for a reasonable amount of money.
This particular remake of a classic Marshall is pretty much identical to the original and has a few upgrades that make it better.
Things like ceramic valve sockets, noiseless (well compared to marshall) transformers and the cloth wiring adds to the sense of luxury.
Ok you never see this stuff but it is kind of comforting knowing that it is there inside.
Once built you then own a classic sounding amp with an expected lifetime of forever.
