Output tubes 6L6G in push pull will drive those two 12" speakers with 15 watts, according to the sales info I had. It is built like a proverbial brick Scheiss-haus, putting it in league with Fisher and other high-end players.
CR-198B is your chassis - The presets are solid mechanical adjustable like a car radio. An optional CR-206 FM tuner (with its own tuning eye tube) can be installed in a delete plate above the AM-SW escutcheon, though I don't recommend looking for one. The DXing on the AM-SW far outshines the early FM tuner 
I know - I have one where I recapped the entire chassis and FM chassis as well, that has its own power supply. It is one awesome radio when connected to just a 15 foot antenna, the filter really makes a difference  I had to rebuild the bottom of the cabinet, it was in a flooded basement, then put concealed casters on so I can roll it out on my porch.
Your stock record player may be only 78 rpm, the original in my Berkeley was replaced by a newer Magnavox Custom that played all four speeds. I use a stereo ceramic cartridge that is available from V-M as Pfanstiehl P228-DS73. If you play only 78, this can also replace your Webcor's original crystal cartridge if its shot.
First get the schematic from Riders, or have a good look at all of those cap values, order a replacement of EVERY wax capacitor and EVERY electrolytic. Don't save anything and check the resistors, Magnavox used crappy ones just like RCA that drift high  blueprint this worthy set by changing out-of-tolerance and wax-bomb caps and you will be very impressed. |
Interesting, mine though has a stamp on the back of the chassis that says CR-198 E on it, which I'm not sure what that indicates but I think mine is a slightly later version than yours, also the changer on mine is definitely original to it, and its a 33 1/3 (LP) and 78 RPM only model, its definitely not a later replacement model, from what I can see.
Also This radio has from what I can tell all of its original tubes in it (RCA and Ken-Rad rebadged GE tubes) that all have date codes from 1947 and 1948, which seems to place my unit's manufacture date to 1948 or so.
Anyways I do plan on recapping the radio I was just trying to get a baseline functionality of the unit, because the original cord was bad so I had to replace that, and so far the radio seems to be functioning well with its original capacitors in it right now, but I will definitely replace them.
