I have been contacted by Marcus  McCoshum of Santa Rosa and he wants to sell a much better than average condition Scott 800B receiver in the Chippendale console and with the original Thorens CD-40…Continue

Started this discussion. Last reply by Scott Seickel Mar 29, 2015. 2 Replies

In the process of restoring the Warsaw custom Philharmonic I learned that the record scratch suppressor circuit was not working.  With the help of Bill Liers I was able to fix the circuit but the…Continue

Philharmonic UHF band circuit variations

While in the process of restoring a remote Philharmonic tuner chassis and comparing to a parts remote tuner chassis, I have discovered a major circuit change in the UHF RF circuits.  Unlike as shown…Continue

I am interested in the serial numbers plus date stamps on the scarce post-war Scott Export receivers.  The serial number is printed on a decal located on the right apron near the back of the receiver…Continue

Norman S Braithwaite replied to Denise Horos's discussion Looking for info on speaker cabinet / power supply amp found with Scott model 16 chassis
"Thanks for your inquiry.  No, the amplifier was home made and the speaker cabinet was likely purchased to go with the amplifier.  There is interest in this type of hi-fi equipment, however, so they have some value related to the components…"

Norman S Braithwaite replied to Tony Peterson's discussion Allwave Imperial capacitor values
"EH Scott Radio Laboratories initially produced the AW-23 using Potter 0.1-mfd capacitors then switched to Sprague 0.05-mfd capacitors. There is no difference in performance of the receiver but a slight difference in cost of replacement components.…"

Norman S Braithwaite replied to Dave's discussion AW Drawing High Wattage no Signal.
"The entire tuner chassis should not draw more than about 150-watts from B+.  The tuner chassis bias is not adjustable.  Incorrect tuner chassis bias indicates circuit problems. Norman"

Norman S Braithwaite replied to Dave's discussion AW Drawing High Wattage no Signal.
"500 watts is way to high.  Check the tuner chassis bias.  It should be -20 volts.  Loss of bias will cause the tuner chassis to draw far to much current.  The field coil was approximately 925-ohms. Norman"

Norman S Braithwaite replied to David C. Poland's discussion output transformer for the 12 inch Magnavox speaker for the Sixteen, Masterpiece & early Phantoms
"Dave: I would want to see the tables before ordering the transformer.  Most of the impedance ratios will be duplicate ratios such as 2500:8 and 5000:16.  An impedance ratio of 6000:15 is electrically similar to 15600:39.  Unless…"

Norman S Braithwaite replied to David C. Poland's discussion output transformer for the 12 inch Magnavox speaker for the Sixteen, Masterpiece & early Phantoms
"The impedance ratio is the critical characteristic, not the rated primary and secondary impedance.  The impedance ratio is the turns ration squared.  Therefore, having a turns ratio of 20:1, the impedance ratio is 400:1 (full primary to…"

"Thanks. I wonder if Scott used guarantee tags marked "Allwave Deluxe" for all Allwave Fifteen receivers. Norman"

Norman S Braithwaite commented on Curtis Walling's blog post Scott Allwave 1934 radio -- repairman needed
"Would it be possible for you to post a photo of the tuner chassis so we can verify whether or not it is an Allwave Deluxe as stated on the guarantee or an Allwave Fifteen based on the serial number?"

Berkshire Power Supply / Amp

"FYI, I like to leave the selenium rectifier in place for posterity and correct visual impact.  Generally, the failure mode on the selenium rectifiers is a reduction in capacity (unable to conduct needed current) resulting in low voltages. …"

Berkshire Power Supply / Amp

"There is a clever fix for the voltage increase problem.  The supply consists of a main transformer and a booster transformer.  If the primary of the booster transformer is hooked up to 220v rather than 110v and the secondary is wired to…"

Shielded Grid Wire

Posted on May 20, 2015 at 2:48pm 1 Comment

Shielded grid wire with cloth insulation is not easy to find but is an appropriate replacement for the shielded wire with rubber insulation (now failing) employed in many Scott models.  A roll of shielded grid wire with cloth insulation is currently being offered at the link below.…

That's how sad that screwup made me feel.

Better than some of the celebrity mugshots I have seen. Kinda rivals Gary Busey's mugshot.

Norman, I also meant to include a closeup of the controls area. John

Mighty glad to become a member of this organization.  I look forward to many conversations in the near future.  Currently I'm working with Bill Bryan to find an A.W. 15 to add to my collection.  Incidentally, Norm you have been invaluable at helping me with my A.W. 23 and A.W. 12, dual dial and thank you for the invite.
