need new amp


I'm bummed out. My tube amp keeps f'n up, popping rectifiers and power tubes.When I plug my Marsh amp in everything works fine, but isn't as satisfying. If anyone has recommendations on a new or used tube amp that would match well with my other components, let me know. Any help would be appreciated.My other components are:

Tri TRV-4SE preamp with old Siemens 12at7's and old Mullard GZ34'
Theta Progeny DAC and Pearl Transport
MusicHall mmf-7 TTable, Lehmann black Cube phono stage
Silverline Sonata speakers
Spelts Anti-cables and speaker wires

When my amp isn't blowing fuses it blows me away how beautiful it sounds. I can't afford much more than a couple thousand and want another tube amp, cuz that's where the beauty lives. Suggestions?
