I learned about tube electronics when I was a kid in the 1950s and 1960s.
I still have a fondness for the old vacuum tube style electronics - especially vintage
radio. I restore vacuum tube electronics and I just love to breathe new life
into vintage tube electronics that have been sitting in an attic for 50 years or
more. Using new components that are much more reliable than the older components,
these units can be restored and will work reliably for many years to come.
I have set up this web page so you can see some of the vintage electronics I have
restored. I sometimes have vintage electronics for sale.

We now offer restoration of vintage Philco radios. We concentrate predominately
on 1920 & 1930s era Philco radios. If you have a family heirloom or you
just want your vintage Philco radio restored, we can help you get it working again.
A restoration is different than just a radio repair. A repair will only replace
components that have failed in order to get the radio to play. A restoration
will replace capacitors that are prone to failure and update the electronics so
the radio will be reliable and play for many years. If the capacitors have
not failed yet, they will most likely fail in the future. Restoration consists
of replacement of all failed components, and those prone to failure.
Standard electronic restoration:
- Replace all electrolytic capacitors. Humming in a vintage radio is usually
caused by the failure of the power supply filtering electrolytics.
- Replace all wax/paper capacitors. These are prone to failure and should all
be replaced with modern equivalents to improve reliability.
- Replace out of spec resistors. Over time the values of the resistors change
enough to affect the overall performance of the radio.
- Rebuild Bakelite capacitor. This capacitor is connected across the 110-volt
line and provides RF filtering. These are potentially unsafe and should be
replaced.
- Install in line-fuse. This provides protection to the radio if something should
short out or draw too much current.
- Install new power cord. The power cords are almost always damaged and generally
are unsafe.
- Install Inrush Current Limiter. This prevents stressing the vacuum tubes when
the power is first turned on extending the life and reliability of the electronics
in the radio.
- Replace any frayed or damaged wiring. We have found that most radios of this
age have damaged speaker wiring and sometimes the grid cap wires on the top of the
chassis. These are replaced with a cloth covered wire to maintain the original
look.
- Rebuild pilot light holder. They are generally melted and not working.
- Test all vacuum tubes.
- Align the chassis so it plays at peak performance.
- Extended operational check to insure the reliability of the radio.
Additional restoration if needed:
- Speaker repairs and reconing of speaker.
- Replacement of any bad vacuum tubes.
- Replacement of speaker grill cloth.
- Replacement of knobs. These can be very hard to get!
- Undo poorly done or botched repairs. Over the years many of these older radios
were subjected to poorly done or botched repairs. It can sometimes take quite
a bit to remove these badly done repairs.
Cabinet restoration:
- Glue any loose veneer and cabinet joints.
- Replacement of missing veneer. It is very difficult to match a 70-year-old
veneer and have the color and grain match, but we do the best we can.
- Strip old finish. We try to restore the cabinet finish rather than re-finishing.
This will increase the value of the vintage radio. Sometimes the original
finish is too badly damaged for a restoration. In that case we can re-finish
the cabinet also.
- Stain if necessary to restore color.
- Refinish cabinet.
- Replace any missing or damaged hardware.
Restorations are warranted for one year. If your radio stops working, return
it to us and it will be repaired at no charge. You pay for shipping to us;
we pay for the shipping back to you once the radio is repaired.
Here are some examples of radio restorations.

Cost to Restore a Philco Radio
|
|
Chassis restoration generally runs about $25 per vacuum tube in the radio to restore
the chassis. If you have a 5-tube radio, the restoration cost would be $125
plus shipping. This is a standard restoration and does not include any extras
such as vacuum tubes, knobs, speaker grill cloth, speaker repairs, cabinet refinishing,
undoing botched repairs, etc. Once we evaluate the condition of the radio
we can provide an estimate of the total cost to restore. Cabinet restoration
is on an individual basis and starts at $150 for a table radio on up depending on
the damage and the size of the radio. If we cannot restore your radio, you
will be charged a $25 diagnosis fee plus return shipping.
What we need in order to do a proper restoration:
- Radio must be pretty much unmolested. If anyone has modified the radio we
may not be able to restore it to its original condition.
- It must have all original knobs. Knobs are very hard to get and we don't have
the time to track them down. Sometimes we have knobs available, but not often.
- Power Transformer working and not burned out. It is extremely difficult to
replace a transformer with an original. They can't be found.
- Speaker not badly damaged. Re-coning of a badly damaged speaker can be quite
expensive.
What to do if you want to have your radio restored:
DON'T SHIP US A RADIO WITHOUT CONTACTING US FIRST!
eMail us at vintageradio@swl-remotes.comand
give us the model Philco radio you have and any information you might have on the
condition of the radio. Try to send a picture of the front panel and the back
of the radio so we can see the chassis. Don't plug in the radio to see if
it works! If the filter electrolytics are shorted you will ruin the transformer
or other components. You might also see smoke. Because these radios
were not fused, the chassis can be damaged very easily. This can cause un-repairable
damage to the radio - most likely the power transformer.

Radio Restoration Examples

Philco 37-610 Table Top (Early Model)
|
|
|
This radio had some pretty bad veneer damage to the front on both the left and right
sides. The cabinet was coming loose at the top. Everything is original
except for the speaker grill cloth and the cabinet finish. It is quite a lovely
radio even though the veneer had to be repaired. The original wood is a beautiful
Mahogany.

Philco 37-610 Tombstone (Late Model)
|
|
|
The finish on the front of this model is a faux (photo) finish and cannot be repaired
easily if damaged. Unfortunately this radio had some very bad damage to the
photo finish that couldn't be repaired. The wood underneath was not damaged.
The finish was stripped, and the cabinet was completely refinished. Considering
that the front is not original, it still looks pretty good.
Notice in the photo of the back of the radio that the RF chassis is floating in
the middle of the chassis and is held in alignment with rubber washers. These
were also replaced so the tuning shaft would align properly to the front of the
radio and would not wobble.
The first photo shows what the cabinet looked like when we received the radio.
The faux wood finish on the front was beyond repair.
