Anotaciones

Models 90 and 90A were available in a cathedral, a lowboy, and a highboy cabinet. The chassis was made in three versions - an early model 90 and 90A with two 45 output tubes in push-pull, a middle version with one 47 output tube, and a late version with two 47 output tubes. Model 90 is for 115 VAC 50-60 Hz; model 90A is for 115 VAC 25-60 Hz.

The models 90 and 90A "early" and "middle" have a 4-gang tuning condenser plus 3 tuned IF circuit - both with IF 175 (Rider's change note 8-3). The version "middle", which are above serial number 237,001, of the model 90 and 90A has tubes: 24 RF, 27 osc, 24 1st det., 24 IF, 27 2nd det. rect., 27 det. amp., 27 1st AF amp, 47 output and 80 rectifier. The "late" model 90 and 90A again have push-pull output but with 2 x 47 tubes. See Rider's Philco 3-35 for IF 260 kHz. Applied on models serial B-32001 to B-35000 and above B-53100. They have a 3-gang tuning condenser and only 6 tuned circuits. The same differences can be found for all cabinets, both 90 and 90A: Baby Grand (Cathedral), Lowboy and Highboy (with a stretcher).

The cathedral cabinet is the classic design by Edward L. Coombs, and is similar to the cathedral versions of model 21, 35, 46, and 70.
