Bigbottle Audio MK1 Phono Stage

[speedyj]

Just recieved this today and hooked it up to my Project 6 Perspex SB.

Currently getting no sound output at all. It has 100ohm plugs fitted and I beleive the input/output leads are connected correctly.

Any ideas why I'm getting no output?

Open it up to check valves haven't become unseated in transit.

Just opened it and fitted the valves (they were sent loose) only one is lighting up and still no output from the system.

The ECC83/12AX7 goes in the middle position.

Input sockets are top outer ones, output sockets are bottom outer ones.
Loading sockets are the middle ones. (Not as I would have positioned them)

Was working fine when it left here, you sure you’ve got the interconnects right way round?

Yip, the Matsushita valves go at either end and the Fisher one in the middle [emoji6]

All good now thank you Alan.

Are the 100 ohm plugs good for my Ortofon Quintete Broze. Sounds OK to me but is it optimum?

Hi,

Specs say > 20 ohm so 100 might be ok, you would need to try others to confirm.

I only packed it with the 100s as that's pretty standard, I'll ask Oli for his opinion as he built the stage and the loading plugs [emoji6]

Glad it's now working ok, I should have told you the valve configuration [emoji3525]

Oli says if you need any others he’ll make them for you if you cover costs/postage.

You’ll get him on AudioAddicts Forum as he doesn’t come on AoS these days.
