I think stranded wire is a PIA except in situations where it will ever be be moved or flexed. It's best to have a nice supply of red colored wire with at least 600 volts rating to use where appropriate. And heat shrink generally works great, especially on transformers if you get the bells open and pass it up as far as possible into the windings. I've even doubled up with a larger guage of heat shrink on the B+ windings just to be sure. Then I hit it with a judicous flick of my Bic. Paint them bells, and reassemble and it's nice again.
