BeePre2 Build
« on: May 01, 2022, 01:10:09 PM »
So I’m working on my first bottlehead kit build and have been having a great time (so long as voltage or resistance checks match). I hit a bit of a wall on my resistance checks for pages 52/53. A4 was good (447), A1 was off (591).
B4 and B1 were both off at 247 (should be around 445). I checked back at the DC bird and the measure the same there (beginning of green wire). Can’t load iPhone pic (jpeg).Thanks in advance for your help.

Can you hop on a computer and post some build photos?

I was able to convert the format.

If I had to guess, you've swapped a pair of resistors. What DC resistances do you get at 25 and 30?  (They will take a bit of time to stabilize as the cap charges up from your meter).

It seems likely that you have three 130 ohm resistors on the B side and two 330s and one 130 on the A side.

327 on 25, 129 on 30.

Those should both be 330.  You have a 130 ohm resistor installed where it shouldn't be on the B side.

A big thank you! I’ll go back and check the resistors. Here are a couple pics I was going to post. Thought I had the right ones in place.
