GW Instek GPC-3020 Power Supply
All three outputs are well regulated. It has low noise and low ripple. The control pots give very smooth and precise adjustment over full range of voltage settings and current limit values. I would recommend it to anyone who wants to add a good quality basic bench power supply to their inventory.

Excellent ESR/Capacitance Tester in Small Package
Excellent troubleshooting aid. I have recently started to recondition Tektronix ‘scopes and the ESR 70+ is very effective in rooting out capacitors that need to be replaced. Most times it works fine with the capacitor in-circuit. If the cap measures marginal, lift one end of the cap to get the most accurate capacitance and ESR measurement.
I highly recommend the ESR- 70+. You will find once you have one, you won’t go without one.
I am not associated with Peak Electronics Design Ltd. In any way, and i have purchased my ESR 70+ at my own expense.
