Help with Jolida 302A

[sobreiro]

Hi, all.

I bought a Jolida 302A several years ago but, unfortunately, the manual was missing.
Can anyone tell me the right way to calibrate the amplifier or, in alternative, tell me where I can find the manual online?

Thanks in advance.

Olá Sobreiro!

Is very easy to calibrate your amp...

With a voltimeter calibrated in mV DC ...measure the voltage between the measuring point of each valve (situated in the outside of the cage) and ground (The outside of the RCA inputs or the minus of the loudspeaker connectors).
Make this measure with the volume pot at minimum.
The voltage must be 40 mV DC ...if not ...adjust with the correspondent pot of bias adjustement of each valve.

Um abraço.
