Default Re: KEL84 from the recycling centre

Hi
Nicely done, looking at the PCB it seems to be the Mk1, the only difference being the PCB between 1&2 and also the provision of relay input switching, which you can add if you wish at a later date.
As Bob says matched EL84s are the best way to go and if you can get them E80CF as opposed to ECF 80 as they tend to be closer toleranced than the ECF80, see my comments and FAQ. There is plenty of help here available so if you or your repairer gets stuck just ask.

John
