Title: Identify these caps!
Post by: limit6 on May 18, 2013, 09:47:00 am
Hey, saw Justin Belshe's bassman video and noticed that he pretty much rebuilt his bassman (one of the AB165 to AA864 conversions) and I really love the sound of it in his other videos.  I was wondering if anyone could identify wich yellow caps these are, and where I can get some for myself.  :icon_biggrin:  I've got a bassman 50 that I'm ready to start tinkering with.

Those look like the Malory 150 series to me. They changed the label color to white a while back. Supposed to be the same cap inside.

Doug sells them in his online store.

You are very good if you can tell that is these Malory caps give this sound   by the web / MP3 / and cheap PC speakers .

Not with my ears. I paused the clip when it had the best shot of the eyelet board. The size and shape look like Malory's to me.

Just a guess.

Agreed.

The relative size vs other components, and their form factor (skinny and long, with a small value that was very small) suggests a polyester film cap like the Mallory 150.

There are a lot of brands that make polyester film and metallized polyester caps with a yellow wrap, not just Mallory. But since the 150 is the most well-known type of this cap, that's probably what the guy used.

You guys were right on the Mallory 150s!  Check this out.  Really cool picture diary of his entire build.
