I'm looking to buy a couple of GZ34/5AR4 rectifier valves. They vary in price considerably on ebay. I'm sure the cheapest are cheap for a reason, but some seem to be branded with a UK supplier's name.
Anyway, suggestions for brands to go for please. I don't need anything fancy, it's just for my Wadar amp, but would prefer ones that might last a while. (GZ37 specified for the Wadar but see
this thread.)
Or if anyone has a couple NOS for sale...?
Thank you.
Ian
