Eros test issue
KevO:
Greetings,
I have my Eros all wired and looking good, but it tests out of spec.
When testing resistance on A4, B4 and C4 I read 620 ohms. I was very careful on these crowded C4,C5 connections and they look wired correctly per the photo.
The instructions though (pg. 49) say wire a cap from C4 to T13. The photo shows thaat cap wired to T8. I went to T8.
The caps show 1 microfarad when tested.
Any ideas?
Thanks!

Paul Joppa:
C4 looks like a misprint, all three tubes should read the same 624 ohms +/-2% at pin 4.
The mention of T13 is clearly also a misprint; 13 is the same center terminal but on the third T-strip, not the second which is adjacent to socket C.
Good call to follow the pictures when in doubt; the photographs are of the prototype which is tested and known to work correctly before the kit is released.
KevO:
Hooray!
Thank you!
I have read what was said to xcortes about 130k ohms and he read 200k ohms. Me too. So I figure that isn't an issue.
Also, whenever I test for 0 ohms, I read .2 ohms. I hope that is OK.
I put a new battery and leads in the Fluke. Same result.
This is the most complex component I've built, and want to take this fresh experience to the next kit. A BeePre.
I'll post photos soon.

Kevin,
Look at FAQ #6. Each meter will read slightly differently on zero and infinite readings.

Hi,
Another newbie question. I just did the power test. here are the results.
A Board B Board Goal
KREG 1.9v 1.69v 1v
BREG 96.6v 97.7v 100v
OA 157.8v 157.6v 170v
IA 221v 223v 225v
BA 0 0 0
OB 94.8v 96v 100v
Question: I saw no perceptible 'glow' in the EF86. But after the test, they felt a bit warm. Normal??
Thanks!
