Very nice... I'm a fan of unique case work, very nice...12 volts on the heaters seems a bit high.
12.6v is the normal value for ecc82 (heaters wired in serie).
@Roberval: very nice build btw, very clean looking. I would have wired the output opamp in non-inverting configuration to avoid using such high feedback resistors (it increases noise a bit) but it is only a minor concern.
