Just wondering if anyone can give me some assistance please?

I started the Nava a few years ago and it had to be put aside due to life. Anyway now that I have free time I've been getting it finished. Everything was going great up until the Hihat, rash, ride. I have been testing all the instruments using an Arduino to pulse the trigger point but I got impatient and decided to do these 3 in one hit and was a bit lazy with my testing.

Upon powering on the Nava to test the HH, CR, RD you can hear the HH trigger then when I try to trigger any of them there is no sound apart from a very faint click.

When testing the voltages the first thing I noticed was a missing -14 on IC51 which turned out to be no solder. The second issue I noticed was pin one on IC64 & IC65 was around 13v and dropping ( looks to be that same as this viewtopic.php?f=24&t=1292&p=8303&hilit=c133+c132#p8303 )So I removed C133 & C132 as per the post which fixed it.

Now I seem to be getting some odd voltages on IC51 IC52 & IC67

Another odd thing I noticed is that the HH sound came through once on power up on all of the single instrument channels for MT HT RS HC so Im thinking there is some sort of ground issue??

Any help would be very very appreciated.
