In Reply to: LED BIAS vs LEAD ACID BATTERY posted by ALL DHT on October 25, 2001 at 22:35:12:
Look for discarded computer UPS (uninterruptible power supplies) in your local computer junkyard. Open them up, and measure the battery voltage with a DMM. Those batteries are usually rated 6 V 8 AH.
If the battery has anything above 5V on it, it is in good shape.
I bought several of those for $2 each. I plan to (eventually, when I find the time), use them to power 26 tube filaments, through a CCS.
I hope this tip helps anyone who needs 6V bias.
