Philharmonic tone control.

Started this discussion. Last reply by David C. Poland 1 hour ago. 16 Replies

As I understand it, on the Philharmonic, the tone control is part of the sensitivity control.  And since the latter is switched out when on phono, it means there’s no facility for a treble cut on…Continue

Problem with Philharmonic.

Started this discussion. Last reply by Norman S Braithwaite Feb 19. 13 Replies

I know it’s notoriously difficult to diagnose faults remotely, but I’m a bit stumped and so decided to ask. My philharmonic has developed this problem: essentially, it’s behaving as if it hasn’t got…Continue

Philharmonic with Capehart 16e

Started this discussion. Last reply by jonathan dollimore Feb 5. 7 Replies

I have decided to part with my Philharmonic and Capehart 16E. Both were professionally installed in a custom made cabinet made in London in the late 1930’s. I am in East Sussex, in the UK. I have a…Continue

Philharmonic tapped volume control.

I posted about this a few weeks back, looking for a replacement.I’ve been unsuccessful in finding a replacement, and nor can  see how to fix the original. I’ve dismantled it and can't see any damage…Continue

"Hmmm. Scott, that is a lot of Philly's. Mine is KK-237. Been some years since I had my pointer Philly on the bench. I just looked at my 1937 diagram. I see the 5 caps composing the stepped treble control just after the bass tone reactor. -…"

"David, I don't know what you are speaking of.  I currently have about 10 Philharmonics and have had at least 6 to 8 that I previously owned and have sold.  Dial pointers that I have had, or still have currently include KK-71, KK-86,…"

"The sensitivity control adjusts the sensitivity of the receiver and in the minimum sensitivity position switches to phono input.  When phono is selected, the signal from the radio is excluded.  The sensitivity control does not affect…"

"The potentiometer associated with the selectivity control adjusts bias to compensate for a change in gain when adjusting selectivity.  This keeps the volume of the receiver approximately constant while changing selectivity.  Unless, of…"

"Scott - interesting. You have a real early production example? maybe with 83V rectifier? Mine is early 1938 with double KK prefix set #. has VR tube behind the tuning cap. has the treble control as I described"

Scott Seickel replied to jonathan dollimore's discussion Philharmonic tone control.
"There is no treble potentiometer anywhere on the dial pointer sets.  The selectivity control has a series of 5 mica capacitors on the back of it to help change the tone, but the lack of treble problem was addressed in later sets. "

David C. Poland replied to jonathan dollimore's discussion Philharmonic tone control.
"Yes. The treble control (potentiometer)  just rides on the same shaft that controls the selectivity mechanism. The selectivity mechanism is the set small air caps across the back of the chassis that tune or de-tune the IF amp and is part of the…"

"Thank you David - as always, and sorry for my obtuseness here: in mitigation: my Philharmonic tuner has been down for the last 6 months and better minds than mine have  been unable to find the fault. Which is why I’ve been playing around…"

Kent King replied to jonathan dollimore's discussion Philharmonic tone control.
"Definitely place them based on your review of the specific set. I'm working on a remote control Philly, and as Dave noted, there are differences in the RC sets because of the mechanical parts. But I have seen other differences over the years.…"

"David, thanks for the control explanation! I am working on installing a Philly into a cabinet that originally held a Phantom, and I will double check the escutcheon positions before I install them. I was going to position them as per a photo from…"

"Jonathon, For your pointer Philly: The BASS control is lower left of the tuning knob. (be sure you replaced the 4 caps inside the bass tone reactor, inside the rectangular chromed box between the expander 6L7s and 3rd audio 6J5s). IMG_1204.JPG The…"

jonathan dollimore replied to jonathan dollimore's discussion Philharmonic tone control.
"David, yes, what you describe is what I have, although my scratch control isn’t working (mine is a pointer dial philharmonic). That is, the phone switch is on the sensitivity control. And there is no separate tone control."
Sunday
David C. Poland replied to jonathan dollimore's discussion Philharmonic tone control.
"The radio/phono switch of the Philharmonic pointer model (and early BOL dial 6 control models) is on the sensitivity control pot. (below band switch, to the left). Later BOL dial 8 control sets would be the same. Thus, when fully counter-clockwise…"

Russ Webb replied to jonathan dollimore's discussion Philharmonic tone control.
"On the Phantom I just finished, the scratch suppressor on/off is at the high sensitivity end of the sensitivity control - which isn't good. If you turn on the scratch suppressor while on a shortwave station you can hear the receive level come…"

Norman S Braithwaite replied to jonathan dollimore's discussion Philharmonic tone control.
"The Philharmonic has separate bass and treble controls plus a record scratch suppressor.  All of these controls operate completely independent of the sensitivity control. Norman"
