Sylvania GB 5751

Tubes Asylum

Questions about tubes and gear that glows. FAQ

I have some Sylvania GB 5751 tubes with grey plates, 3 mica spacers and large, D-shaped getters. They have gold lettering and steel pins (not gold-plated). Are these 50's vintage or later? Also, how do they compare sonically to the 3MBP Sylvania 5751's that are going for so much $ these days?
