New 50 watt build

[Structo]

I have read that the Ceria chassis are a thinner gauge aluminum.
Plus they are a non standard width.

New knobs

[CHIP]

Steve,
those are cool, where did you find them? I need some knobs for my D'lite since i took those off for my new amp.

[67plexi]

The Combo cabinet in the works, Tolex and grill cloth is on the way.

I built the cabinet one inch taller to accommodate a 15” speaker.

Will build a 12” and 15” speaker baffle board to see what works best.

[David Root]

Nice knobs, and nice tube line-up! I also like the VOX style combo cabinet, you can slide the amp in and out.

Let us know how it sounds with those vintage tubes!

[dcribbs1412]

looks great cool knobs...gotta ask, can you divulge the source
15" is a cool idea
covering it with voxish grill and suede?

[67plexi]

Time to paint it black. The 15" speaker fit.

[67plexi]

Tolex time.

Where are those round knobs (front panel) available from and how close are they to the real thing?

Looks good so far!!..What kind of 15 do you have in mind..Here are my faves in current production ceramic

EV15L
Delta Pro 15 and believe it or not the Eminence Legend ain't half bad for the money and a bit lighter too..
I recommend a beam blocker if you go w/15 thought I'd mention.. Have Fun!!

FWIW..I tried mine w/oval back and closed back acoustic suspension..I much prefer the AS

closed back acoustic suspension..

I haven't heard of the acoustic suspension part of this term before, is this more than the typical closed backed cab?

Let's not forget about the knobs?

Mark..What do you mean by more?..

[Structo]

I think they used to call closed back Hi Fi speakers acoustic suspension since the speaker is cushioned by the enclosed air.

Mark the knobs are Alcoknob KES-700AB made in Japan. Pre Fukushima.
The 15” speaker is an Eminence sounds good out of the cab. Will see how it sounds in the cab today.
I’m working on a 12” baffle if the 15” speaker doesn’t work out.
Still waiting on my tolex and grill cloth, brown alligator and fender wheat grill cloth.
Hope to finish this week; I have a show to play on the largest stage in town this weekend.
If not I will use #183 100 watt and #124 100 watt.

Thanks for all the kind comments

Steve.
