[Amps] T/R schemes in Homebrew Amps

Just a simple question....

What are most of you homebrew amp builders using for TR switching in amps?  PB relays?  Vacuum Relays?  PIN diodes?

If you are using Vacuum Relays....and are using surplus ones that use 26 volts, do you have a separate PS to run those relays or are there any tricks that you use?

How do you handle timing issues as well....so there is no or little hot switching?
