Found this high end 15 tube Philco virtually in my backyard on Facebook Marketplace. Forty mile round trip and I now have in my possession. The cabinet is solid and the finish isn't bad, I think it will clean up nicely. According the published reports 35000 were made, but of that number most were the Deluxe model so this example is somewhat hard to find.

Beautiful radio, Larry!

One of my favorites. I love the way the whole front of the radio slopes back slightly from the foot to the top. The sides are very slightly trapezoidal, but it's subtle. Really hard to photograph the effect.

Nice one, Larry.
I much prefer the standard dial over the more elaborate deluxe version.

Very nice. Would love to have one myself. Suggest you quickly order your RF sub chassis rubber parts while they are still available!

I own a standard version of the 37-116 that I bought back in the late 80's. I rebuilt the chassis and replaced the grille cloth, but the finish is still good. Once the chassis is rebuilt they are great working radios. Harry

I'd rather have the basic than the Deluxe. The Deluxe tuning mechanism is a pain to repair.

Agree, plus I just prefer the appearance of the standard dial version. I had one of the deluxe versions for a few years and just never could get myself to like it.

Nice one Larry, I too like the standard version better.

I found this one in 1993 when I didn't know the standard dial version existed. I was surprised and grabbed it for $100!

Good looking original finish Steve, I cleaned up my cabinet with GoJo and 0000 steel wool, waited 24 hours and gave it 3 coats of semi gloss lacquer. Hs some character marks but for it's age pretty darn nice.

Like that figured veneer on the pilasters.

That looks very nice, Larry. I like that you can preserve some of the original coloration and character of the old finish.

Do you wipe down the old finish with any mineral spirits or other solvent prior to applying the new lacquer?

I wipe the cabinet with a dry cotton cloth after finishing with the GoJo, let sit for 24-48 hours then lacquer.

Went through and replaced all the tubular capacitors, electrolytics and dug out the bakelite blocks. Had to sort out the power supply hack. Someone had replaced the lytics with NOS cans and wrapped them in black electrical tape. The speaker had a couple of tears I repaired with silicon and wood glue. The off on bass turns the radio on but I don't get the bass response I was expecting, the switch doesn't have the second click so I suspect a failure. Gonna go over the alignment one more time maybe the grill cloth I ordered will be here by then and I'll box it up and enjoy using it for awhile.

You probably already know this but there is a capacitor in the RF sub chassis that sometimes fails resulting in the lower am band losing sensitivity. This capacitor is difficult to access but doable.

I expected a big bass response not getting it. The switch was soft, I disconnected the leads and manually ground them still no response. The only thing I've found is the volume control reads 5 megs, the tap reads 2.5 megs all of the other components in that area read within 10%. Any ideas, thanks, Larry

I wish I knew how to help from here. Its possible the volume control could be at fault. I wouldn't expect that poor of performance from the value you have given, but its entirely possible especially as you said the bass switch doesn't seem to do anything.

I looked over the schematic, and nothing jumps out at me.

Are all voltages on the audio stages within reasonable tolerance according to the schematic?

Assume you replaced all the capacitors in the tone control network. Possible incorrect value installed? I would verify that first.

No bass suggests a low coupling capacitance. Is there sufficient gain, e.g. is the volume control not cranked up high?

After checking the connections and voltage in the audio again, I turned the speaker over and had it face up and could detect a change, not as pronounced as I imagined it would be, maybe when I get it in the cabinet it will have the bass I was expecting. There is a wooden cone in front of the speaker along with three passive radiators for a reason I expect!

All boxed up and ready to enjoy, big, heavy and nice looking if I may so!
