Just when you thought it couldn't get any better....

[ecca]

.............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 !

Hi Ecca
What would it cost to bring my unit up to date??
All the best

This sounds interesting - were you using 12AX7/ECC83 valves before?

I'm curious because the 5670 has a different pinout.

Hi Roger

The valves that come with the pre amp boards ( sold as audio pre-amps) are Chinese versions of the 5670 not the ecc83 types you would expect to see in valve guitar amps

So no probs with the pin-outs

I don't see why the board can't be modded to take a ecc83 but not sure what would be gained over these GE ones for the effort of doing that.

I bought 2 GE 5670 off ebay for £10 (thanks Ecc) works a treat.

Are these valves direct replacements for what is in the unit at the moment? Is it an easy swap?

[ecca]

Yep, sure are.

I'm still in the USA for another week, so I'll check it out when I get home.

Very easy swap Alan. I use rubber gloves to keep any greasy residue off the valves which can cause cracking. Just checked Watford site USA GE 5670 are £12 each
