.............It just did.
There's an even better valve to be had for the Valve Eccamatic.
It puts a little more zing to the thing.
We have Dick Cruddas to thank for this.
The valve is a GE 5670 2C51 double triode and 2 are required, an added bonus for builders is that the valve is shorter in length than the 6N3.
I've today finished another unit and done a A/B test between the original 6N3 valve, a recommended Russian replacement and the GE5670 2C51 and there is a noticeable improvement
with the latter.
I'll mention no names but, Peter, it sounds even more brilliant than it did before I fitted the new valves to your unit !
