SSS#002 low voltage in original drawing

Thanks Martin!

there was no ground connection from the amps send jack sleeve to the ground end of the input transducer (black cable coming from the coil). The sleeve of the tanks input jack is insulatet to the chassis. Only the return jack of this tank is not insulated. They do it that way to prevent a ground loop.

Wow nice build! What are your chassis dimensions?

[larsvictor]

Hello Erwin, thank you.

Dimensions are:
66 x 21 x 7 cm

That's what I was referring to above re "carrying the ground through" from the tank's input to output. So I guess all you had to do was ground the shield on the send cable, yes? BTW, 1 ohm is about right for DCR on an 8 ohm input Z tank, but I don't trust measurements in that range unless specialized equipment is used.

Ha...don't get me started with jack/chassis ground connections


Glad you've sorted it.

Exactly!

Working on the cabinet...

Nice touch on the integrated fan to cool down the PT

Wow! Great looks Lars.
I presume you take a Evm12l as choice for speaker?

[larsvictor]

Thank you, guys!

Yes, the EVM 12L is already mounted.
