I found something interesting today.
A decent gut shot of the reissue.
There is a Blue, Grey, Green, Gold (6.8M) resistor, with a 1M resistor next to it.
Since there are no other 6.8M resistors in this circuit....I would imagine that these are R34 and R38.
So...the reissue uses the same values for the gain of IC3. (LFO signal gain)

Also....I was comparing the 1482 drawing and my drawing....
Did you use a 270K for R1 as in the 1482 drawing?
I've verified R1 as 100K on the reissue board as well as the older model 7 boards.
A 100K for R1 will give you gain of 1, the 270K will give you about a 1/3 of that.
That may have been the cause of your volume drop.
I recall you addressing that issue by raising the value of R49
The differences that I see between the 1482 and the model 7 all appear to be improvements or fixes.
