Well, I haven`t seen internals of TA-03 yet but first thing to do - replace all electrolytic capacitors, especially ones with no-name or unknown brand! You probably don`t belive it (I also didn`t belive it in case of T1) but it could provide You with greater improvement than getting new tubes. Also, tube-rolling is freaking addictive and costly! I ended up spending money that I don`t want to even mention. But I got some luck and got high-end tubes with very little money. In the end, I ended up with about 75 tubes ! LOL!
But it's so much fun, he sure needs to put top line caps in and of course I'd go right to finding some NIB CCA's
