Re: Is the ECC40 a direct drop-in replacement in the DRD circuit?

195.93.21.66

Kind of gives me goosebumps to think the DRD's could be taken to another level of performance with just a simple socket change. >>

I've seen two rimlock sockets - I have loads of the ordinary ones which are slightly bigger than a 9 pin socket. I have just a single pair of ones with ceramic base which are a straight drop in to a 9 pin hole. No doubt these can be found in Europe somewhere but they are certainly rarer. They would make the conversion less problematic - it would be a drag to file out the chassis holes.
When I originally did a load of listening tests on 9 pin valves, I used the ECC40 in an adapter I made so it plugged into a 6922 base. I have a few ECC40s if anybody's interested. I'm in London UK. Andy
