Picked up tickets & cash at L2.
Clear
Arrived at PSC about 9 AM. Paul Bradbury already there. We ran in two new 9-cord cables between the pulpit & radio room. Sldered in six jacks at each end and checked them out. We next put in 4 Nr. 16 plastic-coated wire for the new speakers, connected the Scott and an audio oscillator. The crossover network seemed to operate — 12 Db/octave altho we have no audio wattmeter or microvolt meter, or equipment to measure intermodulation distortion. There seems to be a quick tendency to generate feedback. We put a radio at the radio choir position and ran it thru the new speakers — they sound quite good. Pit in a switch to cut out the column speakers, and made 3 new connecting cables. The S-C amplifier still picked up FM and buzzed; we tried to isolate it but couldn’t. Put the Altec back in and didn’t hear any buzzing after 1-1/2 hours of listening.
Ken Olsen came in about 3 PM as we were putting on the audio oscillator. He had a line diagram for study.
Took my black shoes to Jordan’s for rebuilding. Took the red ones to Esart’s, where I got them in October 1942, to get the left one rebuilt 1/2-size wider; they will refer it to their shoe-maker.
Left PSC at 5 PM and managed to get to Sears/Lex to pick up my front shocks for the Willys & a Ford fuel pump at 5:35! Got home about 6:45 after stopping at the Lab to get my tickets & travel mtl. for Monday’s trip to El Paso & Alamagordo.
Put the shocks on and drove around to the PO — I think they help quite a bit. Put the new fuel pump on the Ford, using the old Ford filter. This should eliminate the carburetor stoppages at low contents of the gas tank.
Finally got to bed around 11 PM.
Ken Olsen took the S-C amp home to go over it again.
DCH went off to Newton to see his girlfriend in the afternoon w/o doing his studying first — he had to stay home in PM from Dr. Boardman’s party
