Wanted to share a recent completed restoration. The first of several Triolian models introduced in the 1930's, this Sparton model 28 below has received a full electrical restoration. I changed all resistors and capacitors as well as a bad audio input trans. Wood finish is original and has only received a polishing with a micro-crystalline polish. Unbelievable sound due to four type #47 output tubes and three speakers! This unit has a total of 155 square inches of diaphragm surface. Broadcast only, set sounds great with plenty of tonal range and sensitivity across the band! 3 speakers for 1933, very impressive for the time period this set was introduced to the public. A rare set to come across in today's market.

Video of the set playing:

Jon, that is absolutely beautiful!

Hard to believe the original finish made it so long. Sparton really used a poor lasting finish on their sets of this vintage.

Now I need to get mine done.

Thanks for sharing! :D

Beautiful radio! After working on several compact All-American 5's in a row recently, that roomy under-chassis looks delicious to me. I bet it sounds fantastic in person!
