RG400 cable is 50 ohm impedance regardless of its length, but that is not at all important for audio frequencies. It's capacitance is spec'd at 29.4 pF/ft.
Yes you're right. Sorry late night misinterpretation.

(RG-400 is Quite a Loss'y cable.)

Good to hear that your 2nd Gen has come to life Dr d! This is yet another amp on my 'must do' list.

On the RG400 front, if any euro guys know of a good supplier I'd love to know. This is the one ingredient missing from my #102 amp.

Cheers,

Paul.

If I were you I wound just look online at UK shops and look at their bulk cable data.

Look for the pf/ ft rating, although it may be given in pf/ meter.

Something around 30pf/ ft would be equivalent.

BTW, I don't use RG400 on my amp.

I use short patch cables like you use on a pedal board to go from the
Dumbleator to amp.
Then I have fairly long cables to and from the pedal board back to the D'lator.

I believe I used Mogami W2524 for that.
It has a capacitance of 39.7pF/ Ft

Don't let that smoke out!

Here's a clip of my amp through the Dumbleator, reverb and tape delay...

first half volume is turned down on the guitar, second half volume turned up, nice grumbley spanky tone from this Asher T
