hi, just checking with you all to see if my resistance checks out for 300b build.  it appears to be pretty close when comparing amp A and amp B so if they are wrong at least i was consistent. except for oL in 14 and 15 (multimeter fluke 115) when compared to the manual.

as follows:

term  amp A       amp b    manual
5       0.997k     0.998k     1k
6       1.111k     1.107k     1118
7       2.48.7k    248.9k     249k
9       289k         289k       124k*
11     6.7m         6.7m        3.0m
12     28m          26.8m      5.6m
13     0.3            0.3           0
14     oL             oL            9.2m
15     oL             oL            15m           
19     289k          288k       128k*
20     248.5k       2.48.5k    249k

A1     1.01k         1.008k     1027
A3     248.9k       249k         249k
A4     1.01k         1.008k      1028

B1    0.4             0.4            0
B2    9.68k         10.06k       8.2k
B3    248.7k       248.7k       249k
B4    290k          287k          130k*
B5    0.3             0.2             0
B6    289.5k       288k          177k*
B7    225          214.5          220

appreciate any help.  thanks.

Your resistances that are off aren't particularly alarming, I'd move on to voltages.
