Yuck — Not mine<\/div>\n

In the AWA Bulletins that Armand gave me at Winterfest, I saw mention of an AWA PC Board intended to allow for the upgrade of the venerable Heathkit HP-23 power supply. <\/b><\/span><\/p>\n

I have an HP-23B. It came with my HW-101. I replaced the capacitors in the supply many years ago, but they were of marginal voltage specs back then (I think I was in the Dominican Republic) and they have likely dried out considerably since then. I am nervous about firing this thing up. I fear for the big transformer… <\/b><\/div>\n

<\/b><\/div>\n
So I’m going to order the AWA’s upgrade PCB. <\/b><\/div>\n

<\/b><\/div>\n
Of course, the danger (!) is that this could lead me back into the world of high voltage thermatrons. That HW-101 has been taunting me for years. It NEEDS restoration. The first step would be to fix up the Power Supply. <\/b><\/div>\n
