The Philharmonic has two eye tubes, the expander has a 6e5, and the tuning uses a 6g5,as the 6g5's are getting harder to find and there is an abundance of 6e5 tubes, both from Russia and Japan,this…Continue

Some of the lamp covers were missing from my Philharmonic, so I thought that I would share my method of making a similar part,in the photo below, from left to right we have,the metal blank, the die,…Continue

"Dave; Using Norman Braithwaite's instructions is the way to go, nice and easy to follow, don't forget to disable the agc first. You can use a wobbulator, the way I did, but you have to take into account the variable IF bandwidth, there is…"

mike hadley replied to mike hadley's discussion 6g5
"Well this is embarrassing, not only was the original schematic wrong, I placed the resistor in the wrong place. the extra resistor is connected between pin three, the grid of the eye tube and to chassis, making a voltage divider, I have pinched a…"

Scott Seickel replied to mike hadley's discussion 6g5
"Did you fit a small 1/4 watt resistor in the socket  easily Mike?  And on a different note, how is your power transformer doing on 50 Hz?  Does it get fairly warm? I believe the late transformers were painted black to help dissipate…"

David C. Poland replied to mike hadley's discussion 6g5
"That 1 meg resistor is usually hidden in the socket base. Tight fit. Running another wire from pin 2 to ground be a challenge and a bit unsightly even if wrapped around the eye tube cable. Go for a NOS 6G5/6U5.  Try radio club meets, too. "

mike hadley replied to mike hadley's discussion 6g5
"I find that the 6e5 with the added resistor works really well as I have two nos Japanese tubes fitted to my Philharmonic, The tube is set to close on a strong local station, there is plenty of action on the shortwave bands, I did my initial tests…"

Scott Seickel replied to mike hadley's discussion 6g5
"If the 6E5 works decent with the added resistor, why not.  It is easily reversible.   I would never go so far as to change to an octal socket for the Russian version.   I have been successful finding 6G5/6U5's on E-bay that…"

6g5

The Philharmonic has two eye tubes, the expander has a 6e5, and the tuning uses a 6g5,as the 6g5's are getting harder to find and there is an abundance of 6e5 tubes, both from Russia and Japan,this makes a great is a temptation to fit one of these to the 6g5 socket,yes the tube has the same pin out, yes the tube will work after a fashion, but the tube cutoff voltages and curves are different,please see the chart below,…See More
