Frequently Asked Questions
Renovated Radios, LLC specializes in reproduction parts for antique vacuum-tube radios, primarily from the 1920s through the 1960s. I make over 350 different parts, including radio knobs, rubber grommets, washers, and specialty rubber components used in vintage radios.
No. Renovated Radios does not offer radio restoration, repair, or refurbishment services. This site is devoted entirely to making reproduction parts to help collectors and restorers keep vintage radios working and original-looking.
Parts are intended for antique vacuum-tube radios, most commonly from the 1920s, 1930s, 1940s, 1950s, and early 1960s. Commonly supported brands include Zenith, Philco, RCA, Silvertone, Truetone, Westinghouse, Motorola, Stewart-Warner, Arvin, Belmont, Detrola, Fada, Majestic, and others.
I currently make 350+ different reproduction radio parts, and that number continues to grow as new molds are added.
Not all molds are indexed by model number online. I have thousands of molds already made, and many parts may exist even if they are not listed by model.
If you don’t see what you need, use the Contact Us form and include:
Radio brand and model (if known)
Clear photos of the part
Measurements if available
Where the part is located in the radio
Yes. Clear photos are often enough to identify a part or check whether a matching mold already exists. Photos from multiple angles are especially helpful.
Reproduction knobs are made to closely match the shape, size, and appearance of the original parts. Minor variations may occur due to material differences and age-related changes in original knobs.
How do reproduction knobs attach to the radio?
Knobs are finished with either:
a spring steel fastener, or a set screw
In some cases, a reproduction knob may be modified to use a readily available fastener. This does not affect the appearance of the knob.
It is strongly recommended to order a complete set when possible. Even accurate reproductions may not match aged originals perfectly when placed side by side. Ordering a set ensures consistent color and finish across the radio.
No. Wood-style knobs are simulated wood knobs made from plastic and finished to resemble aged wood.
They are made from brown plastic and then wiped with a black mixture to fill the grain. This creates an aged wood appearance that collectors have been very happy with.
This is not recommended. When compared side by side, simulated and original wood knobs will usually differ. Simulated wood knobs should be ordered as a set for best results.
Original rubber parts often harden, crack, or crumble with age. Replacing them improves:
-wire protection
-component stability
-vibration control
-long-term reliability
Most rubber parts are not noticeable once installed, but they play an important role in safety and proper function.
Often, yes. I have thousands of molds already made, and many are reused across different radio models.
If a mold does not already exist, I may be able to make one if you can send a good original part. There will be a charge for creating new molds.
No heat is used during curing, and great care is taken during molding. However, I cannot be responsible for extremely fragile or deteriorated originals.
Parts reproduce exactly as the original appears. Minor scratches can sometimes be buffed out, but chips or cracks may carry over into the reproduction. If the original is in poor condition, reproduction may not be worthwhile.
All molds become the property of Renovated Radios, LLC.
Color matching is possible, but only on an individual basis. It is very time-consuming, expensive, and usually not cost-effective.
Ordering a full set is faster, more economical, and ensures a consistent appearance. This recommendation is about quality and efficiency, not selling additional parts.
