DIY / Vintage JBL Documents - Cabinet Construction and Loudspeakers
« Last post by Watson on Yesterday at 04:11:00 pm »
While unpacking some moving boxes I ran across these two vintage docs from JBL and thought others might find the info interesting.

One is about speaker cabinet construction including port location and size.  The other is about their musical instrument speakers.

Enjoy!

The Triode power transformers are superior to the originals as it is rated for more current. The original Sunn power transformers from Dynaco were not rated high enough and failed. The Schumacher power transformers were a bit better in that respect.

The original Sunn output transformers, especially the Dynaco ones, were excellent, and many people grabbed Sunns when they were really cheap and used the output transformers for their hi-fi projects, so finding original Sunn output transformers is a long shot. The Triode transformers are excellent quality.

Controls look right, though, don't they? Not the locations, but the labels.

Have you considered the Triode clone tranny?

Doesn't look like a Sunn amp at all to me. It just has a Sunn sticker on it from what I can tell. The tolex is all wrong too.

Looks somewhat like a Coliseum Bass. Do you have a picture of the back or know how wide it is?
