Just finished a trio of Bogen DB130 amplifiers. I did a full restoration on these. While I'm not a body and paint person, I think I did OK. Two of them were in decent shape the other needed quite a bit of work done. After several cleanings, they all received a full recap, some getting new topside capacitors others getting re-stuffed. All the mechanicals were inspected, thoroughly cleaned, and lubricated. Rust spots were sealed with Por-80, just in case. A couple potentionmeters needed replacing, a few resistors. The Selenium rectifiers were appropriately thrown into the trash and replaced with 1N5408s. Line cord and line capacitor were replaced with the latter being a proper safety rated capacitor.
I spent way too much time on body and paint trying to get the chassis' decent. As, I said I'm not a body/paint person, imperfections can be found. I don't have a paint booth, so rattle can and inclusions it is. I'm open to all criticism, critique, and 'nice job'.
Why?
I like the look of these. The stubby tapered legs just screams 1950's. The gold was a bit much though, so I toned it down. How many amps have 7 EQ settings? Also, the Heathkit A7s didn't fit with the aesthetic.
Paint
Legs: Flat white with Tamiya TS-45 Pearl White
Chassis: Dupli-Color BCC033 Champaign, Clear topcoat
Faceplate Surround: Dupli-Color BCC033 Champaign, Tamiya TS-45 Pearl White, clear topcoat
Below I will address them as Bogen 1,2, and 3. The photos in the albums may have gotten mixed up. It was hard to keep track of them. Chassis parts (faceplate, cover, feet)may have gotten swapped. To avoid the confusion, the newish film radial capacitors from Bogen 2 were applied to Bogen 3. They tested good and sound good, to my ears.
1 and 2 had the 6AV5GT replaced with 6FW5
Enjoy the mess!
Bogen 1 - keeper
This was by far the cleanest of the three with very little oxidation and rust. It had been dropped at some point in its life resulting in the front corner being compressed a bit. You can see a closeup of the face plate surround that required a spacer. Previous to my ownership someone had recapped the power supply capacitors but left it untouched otherwise. You can tell the before and after by the lack of manufacturer's mark on the replaced multi-cap electrolytic.
Bogen 2 - keeper
This one had been molested in a previous life. It had been recapped (poorly) and had a capacitor tree built out of bailing wire and cold solder joints. The before pictures are bit gruesome. Other than the electrical hack job, it was in good overall condition. The knobs had some mange but that cleaned up well.
Bogen 3 - for sale
This one had the most electrical and physical damage. The damping circuit previously suffered what I suermise was an unplanned hyperthermic event and left a swath of carbon on the chassis and burned the paint off the top. The balance pot was also missing half of its resistive material and was replaced. The mange on the knobs was pretty bad and took a lot of cleaning.
Rather than clog up the forum with too many pictures I'll include links to the albums on my Google Photos. Don't worry, there's some videos of how they sound from my Klipsch, to my phone, to the internet, to your speakers, so I'm sure the reproduction is perfect.
