The directions for the RF alignment of the Allwave 23 say that you connect the generator to the antenna terminals thru the "proper dummy". Capacitor? value? For all of the alignments I have done over…Continue

Hi Thomas, I have accepted your friend request! I live in SE Michigan, NW of Detroit. I have been collecting radios, stereo equipment, TV'S, most anything that contains vacuum tubes, for many, many years. I have recently acquired my first EH Scott radio, a 7 knob Allwave 23, in Warrington cabinet. I have experienced and admired Scott radios for years, since I was first aware of them, over 30 years ago! Always wanted at least one, for my collection, and finally found an affordable one! I have my set basically working, I have to recap the tuner, which I will be doing, as soon as I buy more capacitors.

Hi Thomas, right after I posted my thread I discovered my model is a 310, not a 510.  I was relieved since the 310 did not have the power amp to begin with, and I thought mine was missing.  I removed my thread due to that since it was wasted space...  

Thanks for the comment and tip.

Thanks again-I will give this information to my friend who has the chassis on his bench right now (waiting for condensers).  I have lived in Muskegon 25 years, and while I have been to the Frauenthal many times, I have never had a chance to go when the Damfinos get together.  That Barton pipe organ looks like a bear to operate!  An old aquaintance of mine, Cliff Martin, played it for many years.

Thanks, Thom, you were right-I am looking for a .25mfd @1250v, not 25mfd (wouldn't be the first time I've missed the point!).  Which leaves me with the same problem-where can I find one?

Thom - Actually, it was Norman Braithwaite that put the checklist on here. I don't have a link handy right now, but I'll try to find it and post a link here...

Look for a current drain.

 

My first AW-23 had a shorted primary when I acquired it 15 years ago. (I should have been suspicious of the 10 amp primary fuse  ...  like maybe a proper 3 amp fuse would blow.). Anyway, I recapped it before powering up the first time on my variac. The proper size fuse  would blow when my variac reached about 40 volts. I eventually obtained another power transformer from a rough amp, and the radio ran great. Then a year or so later the fuse blew Christmas day, after it had been playing 3-4 hours ..... same problem as before, blowing the fuse at moderate variac voltage.

 

The ultimate problem turned out to be in the speaker. The red B+ wire inside the pedestal from the speaker terminal strip to the field coil was laying across the point of a screw and made a partial connection at high voltage through the worn insulation. Excessive current was not quite enough to blow the fuse but enough to overheat the transformer,  progressively cooking  the transformer until the primary failed blowing the fuse the day I ran it several hours. I found the problem by close visual inspection of the routing of the wires in the speaker. Corrected the wire location, and the power transformer #3 has worked out fine for many years.
