Hi Paul:
Getting close to finishing my Beepre 2, I did not have a problem on the A4 A1 reading on the ohm meter both terminal got close to 445. But when I reached the part of B4 B1, I got a 500+ value on the B4 but got a correct value on the B1. Not sure what the problem could be. The other thing different here is the 220Ω ¼W carbon film resistor (red, red, brown, gold) to B3. This is not from the original set since I could have toasted it on my previous thread. I bought this at a local electronic store.
Since it is an isolated problem can it be the 0.51Ω 3W resistors on the B4 causing the error?
Hope to hear from you soon, thanks
