Title: Voltage check with Speedball
Post by: Jimb0 on January 02, 2015, 11:35:31 AM

Hello guys,

I just recently upgrade my Crack with the Speedball and had a question about the voltages. Everything checks out fine except for terminal 7. The expected voltage is 100 but I'm getting around 85 volts. Is this too low? Also, I noticed the 4 LED's on the two small PC boards don't light up as bright as the other LED's. Is this a soldering issue?

Looking for your support. Thanks!

James

N/m, the voltage went lower when I added the Tung Sol 5998. With the stock Jan 6080 WC it went back up to 100. I'm assuming this is normal when switching tubes. The only thing that I'm noticing right now is that the 4 LED's on the small pc boards are still dimly lit than the other LED's. Is this normal? Thanks

I also noticed a difference when I built my crack/speedball that some LEDs were brighter lit but I don't recall if it was the same pattern. Main thing for me was that everything measures well and sounds fine.

Big board LEDs draw way more current so they are brighter.
