HH has some issues...no sound...
plus
I missed it when I had a look first time but its missing 3 pop bumper boards..

Don't stress about the pbb's.  If you are happy with original's (rather than Rottendog replacements) PM me your address and I'll send em for nothing...BUT they are original and un modded and havn't been tested working in game but I can test transistor only for you.

RE sound...Does it still have original sound board and power supply for it?  What are the voltages like?  Also was the orange cap replaced in game?
