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

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

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

"Yes, that would be a late model manufactured around January 1947 but likely stored on a shelf until needed to fulfill an order. There will be an inspection date ink stamped on the inside of the station finder commutator shroud (square box on…"
"There were two versions of the Model 800B, early and late. The late version had two chokes on the power amplifier and a revised tube layout. Many of the early version were updated to add the additional choke. The early version had…"

"The tube under the audio output tubes is most likely a phase splitter to replace the interstage transformer with a bad winding.

"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…"
"The Philharmonic has separate bass and treble controls plus a record scratch suppressor. All of these controls operate completely independent of the sensitivity control.

"I suspect the cathode return introduced a small amount of negative feedback to the IF amplifier to improve IF amplifier stability. In every AW23 on which I have worked, one tuned circuit is shunted by a 500k resistor not shown in the schematic…"

"No. It was Victor's finest product when new in the late 1920s. A good portion of the cost of the electrola was the fancy cabinet. It was not unusual for a Scott customer to repurpose a fancy cabinet housing an obsolete piece…"
"I'm not convinced there is a demand problem. All reproduction runs have sold out in reasonable time with the original supplier producing and selling out of three runs. I believe the issue is more along the lines of the complexity of…"
"RCA through the run of AW-23s. The AW-15 and at least early AW-23s originally employed the RCA flat plate 2A3 tubes. I don't recall ever seeing a hot stamp base Sylvania 2A3 in a Scott. Possibly Arcturus for the AW-12s but…"
"Russ, I have plenty of Scott OEM cardboard capacitor tubes. I'm sure I have a 279."
"This sounds like a possible case of a bad ground connection somewhere resulting in hum and allowing the audio signal to travel through a ground wire. Try jumping lugs and terminals that are supposed to be at ground to the chassis using a short…"

Carr Fire
Posted on August 1, 2018 at 11:41am 3 Comments 0 Likes
As some of you know, the Carr Fire has exacted a great toll in the City of Redding and surrounding area. My house and half of my collection was the first visited by the fire in the devastated Lake Redding Estates neighborhood with no advance notice to evacuate and no fire trucks around. Fortunately the house and collection were spared. Unfortunately, however, I have learned that the house and collection of an acquaintance including several pre-war Scott receivers was lost and that another…

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.…

Norman, glad you personally are OK. Threats from fire are unnerving.

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.

- 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.
