Heirloom 41-250
#30

I've pretty much completed the semi-conductor list for my project. I used the 41-255 parts list as a basis. I have not found any parts discrepancies so far. But I do have a question. In the 255 diagram, part 57, a .003 mfd condensor, goes from the white wire leading to the output transformer (58) and to ground. On the black lead, there is part 68, another .003 mfd. condensor going to ground.

In the 285 diagram, condensor 57 does not go to ground but to the black wire. 68 seems to be eliminated. Could someone please confirm the value of 57 in a 285? Out of curiosity, why the difference? Is there a possibility I should not use this variation due to my using the much smaller speaker from the 250?
