Radio Shack wants $30 for their digital multimeter, should I call this good? Is ebay an option? Trying to set the bias on a dynaco st70.
The stock ST 70 likes 1.56 volts. The Curico modified one likes 1.26 v. $30 is a bit much. My Radio shack digital always has dead batteries. It uses watch batteries. I bought my son a Sears Deluxe red digital that uses bigger batteries like 4 aa and a 9 volt. I think it was only $39 on sale and it is really nice. Much better value. I think Sears has an analog one for ~$12.
