phonola: 5567: Hall of shame
Emilio Ciardiello

I moved this topic, started speaking of the Phonola 5512, as new thread to the right model.

Well, in order to examine the power supply section, we find two diagrams for this model. Even if the layout of components is different, the circuits are quite the same. I say ‘quite the same’ because of the different EM4 pin names on the two diagrams.

Power supply section

First of all, we note unusual hybrid solutions. Heaters are connected to taps of primary windings on the power supply transformer, used as an auto-transformer. A separate winding is used, with a half-wave rectifier, to generate the anode supply voltage. The use of an auto-transformer was crazy from a safety point of view, nevertheless quite common in those years, to save on the size and cost of the iron core. Anyway we see that only about one half of the total power, that related to heaters, is handled by the primary side. The remaining power, from the secondary winding, goes to the half-wave rectifier. This circuit, producing unidirectional current flow and then a magnetization of the iron core, requires larger sections of the core itself. And anyway it asks for considerably larger and by far more expensive filter capacitors. We find a 50 + 50 uF, quite rare in those years. Saving on the transformer copper was more or less nullified by the amount of workmanship, required to wind the various sections of the primary, each with different wire size.

Anyway, giving a hasty look at the diagrams, we could have the impression that the designer wanted to offer a brilliant solution to the problem of the galvanic insulation of the chassis. Actually the metal chassis looks fully floating and insulated from the ac mains. But this appearance is deceptive at all: this radio, as most of the Italian sets, can be very harmful for its users.

To follow the possible conduction paths, we can simplify the circuit as follows.

H1 and H2 are the heater pins and K is the cathode of the EM4, regardless of the pin numbering on each diagram. Now we can easily see that the thin alumina insulating layer, between heater and cathode of EM4, in parallel to the 10 nF capacitor, is the barrier that separates one of the AC mains wire from the chassis. This layer is specified to withstand 100V max AC or DC voltage.



Therefore, if users touch the braid of the shielded cable to the record player arm, the same body of the phono pick-up, or even an unprotected metal shaft, maybe due to a missing or broken knob, they are protected by a layer capable of just withstanding about 100 volts. Certainly the designer did not read the EM4 datasheet or missed this parameter at all. I could bet that he specified 630V or more as voltage rating for the 10 nF capacitor in parallel. So we look at an incomprehensible mixture of poor and even stupid circuit solutions to electrocute customers.

Blame on this design!

Henning Oelkers

Dear, Emilio,

maybe there is one Reason for this. Usually the AM Reciever is connected to Antenna and Earth. On fully isolated Radios this is done directly, and in non-isolated it must be done with coupling Capacitors. Maybe it was found, that this solution was better in reducing AM Noise comming from Mains Supply, by reducing the AC (50Hz ) Voltage across the Ground and Antenna  Capacitors.

Best Regards,


Emilio Ciardiello

Dear Henning,

I agree with you on the use of the capacitor from the power line to the chassis. Here we see a 10nF capacitor, probably paper, 630 or even 1000V. I blame the filament to cathode barrier in parallel to the capacitor. It cannot add sensitivity, it can just spark and kill some unlucky users. The designer could use a different magic eye, designed to operate with heater connected to the AC mains, as the UM4. Or he could add a separate 6.3 V secondary winding for the EM4.
