Valve amps, love them, and have had (and have) my share of Hiwatt, SC, Marshall, Vox and homebrew. Well executed amps are things of elegance and beauty (to me anyway, am I sad?). I love the simplicity and ease of repair, which I can do myself most of the time. Downside is when repairs are not DIY or involve transformers. The moment repairs involve a skilled person who makes a fair living, then the effects of new technology start to have a bearing. Class D poweramps are now silly money (Peavey IPR 1600 £219),they can almost be treated as consumables if lasting 2 / 3 years. Think I am going handbuilt valve pre-amp, then class D poweramp. best of both worlds? Must get shot of my SC120, is very tidy and unmolested, just hisses
