38-1 code 121A
#1

Hey all. Just got back to this project after being sidetracked by another (built a motorbike for my brother). Cleaned the chassis up, and assessed the situation. this is a code 121A (any particular reason for the "A" designation?), and the schematics pretty much jibe up with what's in the set, EXCEPT for a couple of anomalies:  1) TRANSFORMERS- calls for 2 smaller ones, and a big one.( I have the correct big one), but calls for a 32-7869 and a 32-7871... I have a 32-7115T between the front large xformer & the rear (which appeared to have a massive meltdown, judging from the amount of resin that oozed from it down to the cabinet. I assume it's fried. The rear is a 32-7671T. Are these compatible? (They seem original...)    2) ELECTROLYTICS (on top of chassis)-- SCH#102 calls for a 2 section (part #30-2201) 8/10 uf- BUT an ugly orange Sprague single 8uf is there in its' place...  SCH#98 calls for a single 18uf, but has a double Solar brand 8/8uf there. ...  SCH#77 (on the RF chassis on top) calls for a 2 section 4/3uf, but has a double Solar 8/8uf there- would that be considered excessive for that circuit?  Under the chassis, SCH#101 .25uf is nowhere to be found, but a single Sprague 8uf is there directly below the oozed transformer, with no ooze on the Sprague, or anywhere under the chassis...  So obviously, this drives me up the wall, and I must acquire the correct Philco electrolytic cans and the correct Philco .25mfd cardboard housing, of which I will advertise for on the sale/trade section soon. Surprisingly, save for a couple non-Philco tubes, that appears to be the extent of "repairs". All else appears correct and original. So the question of the day: Does that "A" designation on the 121 code change the electrolytic can configuration, or is it all sheer debauchery? P.S. I transferred my pics to this computer...Just gotta figure out how to show them here...the instruction book is 392 pages long it appears...(ha ha)
