The bottom line is most of the earlier ones have great potential regardless. Easy to work on and hand wired. Many of the silver face amps I have played sounded good, and when they have some decent old tubes in them even better. I have a 1968 silverface Pro Reverb that absolutely kills. Original Utah speakers, but new reverb tank, caps, and tubes. Had it blackfaced and never looked back. Congrats! The VR is one of the best.
