Reading 38-116 Tube Pin Voltages with Tubes Horizontal
#1

I'd like to record voltages for tube pins in the 38-116 Code 125 I've been working on. After testing tubes, re-capping, and replacing out of tolerance resistors, the radio plays with distorted audio. I can set the chassis upright on the end with the power transformer, secured to a lazy susan turntable. I also have support under the edge of the power transformer so the corner 6L6G tube doesn't touch the turntable. Is there any issue with operating these tubes in a horizontal position? The tube lineup is 6U7G 6A8G 6A8G 6N7G 6K7G 6K7G 6J5G 6K7G 6J5G 6R7G 6J5G 6L6G 6L6G 5X4G; except mine has a 5Y4G in place of the 5X4G.

Thanks,
Larry
