Lamp Limiter versus 0-30V Power Supply
Should I be thinking about purchasing a transformer/power supply or is the lamp limiter that I made perfectly adequate?

Re: Lamp Limiter versus 0-30V Power Supply
Hi Brian
Did you mean 0-30V or 0-300V? If you are working on Domestic Radios usually a lamp limiter is enough as long as you do some basic checks. On older (Pre-war sets) I sometimes use a Lamp limiter and Variac. A 30V DC power supply is always handy and second hand can be a bit of a bargain. Lamp limiter is cheap and easy but bear in mind it offers protection against catastrophic failure due to shorts rather than excess current due to dodgy caps Cheers Mike T

Re: Lamp Limiter versus 0-30V Power Supply
Hi Mike,
I was just looking back over a previous post "tools/equipment that couldn't live without" and may have misread 30V for 300V. Given your aforementioned, I think I will stick with the lamp limiter until we can all get out to the auctions etc once again. Thanks Mike, Regards, Brian |
