HELP With VOX AC100CPH

http://www.ampix.org/albums/userpics/10003/Vox_AC100CPH.pdf

Hi everyone!! ive got this VOX AC100CPH wich suffer some of those ^worst than before^ repairs.

the amp came up with a very low output and stuck in the dirt channel. some hours later i get the schem and i realise that the TCN207 - CON7 / TCN9 - CON9 connections were inverted, :eek: so, the TCN9 with the TCN207 & the CON7 with CON9. :hypno2:

after connecting everything in the right way the amp came to life again, sounds loud and the channel switch does his job too. BUT! an intermitent loud poping sounds appeared. so, its being difficult to get to the source of the POP. i try with new valves and the problem persist, all the voltages on the schem are normal. i think its an preamp issue couse trhough the return the pops goes away.
today i got an oscilloscope so a little tips would be very appreciated!! :hypno2:
