Mark Levinson No 38, Need Help

[Pocoyo]

Dear All, I need help for my preamp no 38

My preamp works perfect for all input from RCA ( even from phono )
can anybody here help me, how to active balance input connection
/ xlr interconnect from preamp input channel 1 or 2 ?

Is there specific way to active them ?

i try several times from channel 1 or 2 ( From DAC and CD player )
but channel 1 and 2 in preamp still " NO INPUT " in the LCD

Thank you in advance, Best regards

When did Mark Levinson start / stop using Blackgate capacitors?

When did Mark Levinson start

Hi Ticknpop, i will try to restart this preamp and use xlr interconnect
in DAC output link with Preamp Input Channel 1 or 2 for XLR

I hope this way will make success

stop using Blackgate capacitors?

Those BG on PCB makes this pre become like crystal
I didnt make any mods again
