I have a S-C Royale wooden mantle radio that has some crook Valves in it. Has someone a schematic that they can scan and email to me please. It is in excellent "electrical condition", but the valve that is U/S, is unknown, as the letters/figures have been rubbed off. I would really appreciate it, In anticipation: John McRae South Australia

Hello John Can you have a go at dating the radio. The tutorials section will help with this. Cheers Graham

Certainly sound like late 40s or later. Can you look on the back for a model number, and provide the numbers for the valves that you can read, and the total number of valves. If the number is rubbed off, put the valve in the freezer for a while, then take it out; condensation sometimes shows up the number.

If it's minatures not octals then the first fully minature equiped was likely 51A11 in 1951. I see no reference to Royale in AORSM's. Marc

Hi John I now have my copy's of the AORSMs. What brand is the radio, In your first post you said s-c did you mean Stromberg Carlson? if so dont bother about what I have written below! The Only referance to Royal is in the 1947. "Garnet Royal" It comes under the 'Denradio' brand name. Just a few things to narrow down the mod of your set: 1. Does it have a transformer? 2. How Many Valves? 3. Does it have short Wave or AM only ‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾ Valve radios, They just don't make them like they used to

Gday Flakes It is a Stromberg Carlson Royale.. It is SW/MW and has 7 tubes. One is an octal 5Y3GT the rest are miniatures. Yes, it has a transformer Cheers.

Might be a good idea to list the valves that have numbers that are legible. 5Y3 will be the rectifier. Most used 6X5 as the rectifier. Check the wiring. Heaters / filaments won't work if the wrong tube is in there? 6X5 heaters pins 2 & 7. 5Y3 Filament pins 2 & 8 on their own winding. Marc

Ok... From looking through my lists it might be: 1. A7211 - (1952) This is a 7 valve set. the rect may have been changed from the 5Z4. It has another octal witch is a 6SN7 as a phase splitter before the 2 6BW6 output valves. 6BE6, 6AR7GT, 6AU6, 6SN7GT, 26BW6, 5Z4G 2. A8231 - (1953) This is a 8 Valve set with a 'magic eye' tube. It has an octal rect 5Z4G and may have been changed in the past. The rest are miniature valves: 6BA6, 6BA7, 6BA6, 6BD7, 12AU7, 26BW6, 5Z4G, EM85 3. A8551 - (1955) Same as above with a different line up. 6BA6, 12AH8, 6N8, 6BR7, 12AX7, 2*6BW6, 5Z4G I have diagrams of all 3 of these radios. You will need to try and find out at least one of the other valves in the set. contact me via email and I will be able to send you the diagrams and other info. Looking through my valve data, The 5Y3G may be used in place of a 5Z4G without much of a problem. Daniel flakelartpg.com.au Disregard all of this... These are all STC sets not Strom. Carls. I must have been asleep at the keyboard! ‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾ Valve radios, They just don't make them like they used to

Two horrid 6N8's possible (double diode pentode) Five anything other than 5Y3, no way. 6M5 I would believe and the only way it would have two is if they were in push pull. 6M5 is an output pentode. 6GW6 mentioned above (minature 6V6) is not pin interchangeable with 6M5. I have seen 6N8 used as a phase splitter. That leaves us to be missing the converter which could be 6AN7, 6BE6, 6BE8, or ......, depending also on the number of pins (seven or nine) Post on A 8231& A8551 are missing the converter? I would think 6BE6 (seven pin)? Things in this set do not add up. Marc

5M6....darn it ...A typo...of course they are 6M5's!, as the miniatures are 6v tubes! the crook tube has 9 pins What I can do, is take a picture of the crook tube..that may help perhaps? cheers. John

Ok well then.... It could be Strom. Carls. 1951 71A31 AC DW 7 455 6AN7, 36N8, 26M5, 5V4G/5Y3GT AORSM '51 278 Its the only thing I could find with the new info. Just to narrow it down a bit more: 1. Is the tone a Switch or a pot. (the above is a 3 pos Switch) 2. The Bass control is also a 3 pos switch. 3. The one I am looking at has 2 speakers running in parallel. 4. Does it have a phono i/p Let me know your email address and I will send you the diagram ‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾ Valve radios, They just don't make them like they used to
