Anyone have a working Philco T-77 ???

How's the performance & sound quality ?

Noticed that it has 7 transistors (which appear to be their excellent Surface-Barrier type), reduction tuning w/air-variable cap, and OTL audio output---and operates on two "AA" cells !

Can't say I really like the styling, but thought it might be a good performing set...

Thanks for any input !

John

Hi John, I have the T-88 124 it's an 8 transistor of the same time period as your T-77.

The layout is horizontal with a longer ferrite rod but it has the same reduction tuning cap with a dial string.

The battery holder looks the same as yours (2 AA cells).

This one has a slightly larger speaker (2 ΒΌ inch)

There's only one Ecap which is still original and works quite well.

Is this your new find? looks like a keeper, don't see them very often.

I have two T-66's, six Transistor sets that came out a year earlier. Excellent performers, which is to be expected from a Philco.

Thanks for info Guys !

I bought it... Ebay pics fuzzy, but looked decent... Don't really like the color or styling (yet), but it is unique---was sold by the inside pic and after looking at schematic... Think the addiction is starting to get a tighter grip !

Will start project thread as usual once it arrives...

John

Got it today---shipped loose in thin bubble envelope, had cracks on edges of both top corners and is dead as a doornail...

Stay tuned !
John

John - Sorry to hear that someone sent you the Philco T-77 in a bubble wrap envelope. I bought a Mignon 6 transistor radio from Antique Radio Forum member Don just for parts (wanted the dial) and he sent it in a Priority Mail box with a carefully built compartment of packing material! I only paid $5 for the Mignon radio and case, plus $9.20 for shipping and the radio still works! I wish everyone was so careful when they send out packages. Thank you Don! John, I'm sure with your abilities, you will get that Philco T-77 working again and looking great! - Mark

I like the color actually, a little crazy glue will fix those cracks.

It is a very unique radio, I hope it's just the usual cap replacement and it will come to life.

Check the earphone jack

Thanks Guys !

Mark---I've had people here (and some on Ebay) send me items including parts packaged like valuable treasures. Always appreciate that extra thoughtfulness !

Rocco---Wonder if Superglue might cloud the surrounding plastic ? They are small enough that I could live with them, just have to be extra careful removing the back cover... Checked the speaker a little earlier (before getting on-line) and it was okay and found that just a touch on outer contact of earphone jack made it work ! Performance decent, but not great (yet)---but sound from that little speaker is pretty good even with original caps ! Volume control is even "wobble" and noise free. Numbers are worn off the tuning dial window and have no idea how to neatly restore them---why didn't they put them on inside surface with the rest of graphics ??? This is a heavy, solid, well-built U.S. made radio and even the knobs appear to be chromed metal !

Hey Rocco,

Just pulled up the T-88 schematic and it has an RF amp stage !

Yes it does! forgot to mention.

I usually apply Superglue on the inside of the case when repairing a crack and nothing shows on the outside.

Were the original numbers silver on your dial?

I believe Letraset makes white stick-on numbers, not sure about silver.

Hey Rocco,

The cracks are right at the "latching" area at top---would be difficult to glue... But they aren't very noticeable, so will probably leave them alone for now.

The numbers are supposed to be silver, but they are a unique elongated style. Maybe a junker with good dial window will come along one day...

John
