EV1 input capacitance

Post by goonybird »

Replace my Phono turntable leads with VDH Thames from Mogami?
Now sound is quite strident at the top end so thinking not enough capacitance
Lead is 103pf per meter arm cables are about 35pf?
But I cant find out input capacitance on my EV1 Circuit Diag only shows 10pf?

So looks like I need to add about 100pf.
Cartridge speci is for 150-200pf

Not sure what the rating is, but I'm also not sure if really matters You can certainly experiment if you find a difference in the sound or if it improves anything by changing the capacitance.

Bought a capacitance meter and it is the EV1 is nearly zero (10pf)
Had these phono splitters lying around. so plug into phono input and TT plugs into rear socket.
Then soldered 100pf in one pair and 200pf into another pair of phono plugs
can just plug into adaptor different values. Also could be used for loading resistors ?
Settled on 100 pf which is about 200-250pf total which corresponds well to the recommended loading of 250pf of the Reson Reca

That solution does make it a lot easier than removing covers, throwing dip switches, and plugging and unplugging. No doubt.
