[ARC5] Find Bad Bypasses in 20 minutes

[cemilton at aol.com]

Hello to the group...……..
 
This may seem slightly off-topic, but in addition to the great information regarding cap leakage on the ARC-5 gear I want to acknowledge KE4RHH's comments on AA4RM, Marty Reynolds.  Each of us knows or has known someone from the ham community that simply stands out from the rest and is the true Elmer we all look up to.  For me, Marty was a personal friend and I saw him 2-3 times a month in Atlanta.  He always had "answers" to everyday equipment issues and had the knack of being able to explain them in terms we could all understand.  Tom, your comments about Marty just brought back many fine memories and yes, we still miss him to this day.  Thanks for your comments and for reminding many of us of AA4RM.  RIP Marty!

"Your post reminded me of a post to the list many years ago, by Marty Reynolds, of Atlanta, who  shared with us  a similar approach to id a leaky cap in ARC5 RX’s.

He removed (unsoldered) the ground end of the two 7k grid resistors, and then applied 250v to that now ungrounded lead, and got a current measurement.

Filament voltage was off during this process.

He then would turn off the 250v power, unscrew a flower pot cap, insulate it from the chassis, turn the power back on and get a current reading.  A lower current reading would indicate that cap was leaky and needed to be replaced.  

Then he would repeat the process for each cap in the RX, and in doing so would identify which caps were bad and needed to be replaced.

Unfortunately Marty passed away several years ago, and has been greatly missed by all of us who knew him. A super nice guy who would keep the Boatanchors Group at the Shelby Hamfest each year spellbound with his stories about military, commercial, and amateur electronics."
