Ungar soldering iron 98 cents
KG2000 oscilloscope kit $199.50
(all tubes, 5 MC, triggered sweep, DC coupled... I had one)
1% axial resistor 54 cents
10% carbon comp resistor 13 cents
1N914 diode $1.50
2N2222A $6.75
12AX7A $1.28
The dollar-value adjustment is about 8:1. So the cost of gumdrop parts is now hundreds of times less than it was then.
My allowance would buy a few diodes per month.
