I will cast out a bet that the plate voltage is run near 400 volts .
When I die, I want to go like my Grandfather did, peacefully in his sleep.

Re: Showman Amp
My 7355 Showman is packed away in storage----- It might be a while before I can get to it, take it to my shop, and test voltages.
They're slamming us with overtime at my regular job so I've closed down my amp shop to outside amp work---- And I have almost no time to work there on my own amp projects.
The pics are old ones I put up on Photobucket years ago.
I can't remember the voltage measurements from when I worked on the amp.
Sorry I can't be more helpful right now.
I keep one of my 6L6GC BF Showman heads in my shop---- It gets used regularly and sounds like a BF Showman should---- the 7355 amp really doesn't match it as far as playing satisfaction.

Re: Showman Amp
No worries, just curious. This has been interesting as I was not aware of this experiment. Sort of like the brief flirtation with 6BQ5's.

I would think that 4 7355s could match for instance the two 6L6s in my BF Bandmaster, that outputs 42 watts RMS, that is unless the OT Leo used was a mismatch for the sake of kicking gear out the door, or the PTs voltage / current combo was lean?
It's just quite odd to offer such a lack luster amp with 2-15" drivers, but who knows what they had in mind, either way it had to be a expensive amp for back then even without Trem or Verb!

Re: Showman Amp
Mea culpa on the 6L6's. I'm no expert on amps.
You are correct that it's 7355's!
I used the online specs for the Showman and not looking at the tubes!
I didn't know there were 'experiments' on the model.
Here is a pic of the tube.
The speakers are indeed 15's. JBL D130's. 16 ohms in parallel. I opened the back to check.
and it was a blonde as I said, unless it was common practice to use blonde tolex and then dye it black??
I am amazed at the knowledge here on The Amp Garage!

Re: Y
This is definitely a blonde. It sits horizontal with the amp on top. I seem to remember some kind of 'pegs' to keep the head in one spot? (Not home at the moment to see).Stevem wrote:Fender never made a Blond 2-15" horizontal speaker cabinet, those must be 12" JBL drivers if they are original !
The first 2-15" cab came about in the black Tolex era, and the cab stood verticle.
I can see the blonde coming through on the corners and there's the pic in post above that shows it unstained.

Re: Showman Amp
gldtp99 posted a pic of his blonde 2x15 above. You can see the "piggyback" brackets are on the long side.
Re: Showman Amp
Yes, this has the brackets on the long side too. I stood it on end because of no room in the garage.martin manning wrote:gldtp99 posted a pic of his blonde 2x15 above. You can see the "piggyback" brackets are on the long side.
Does it matter which way the speakers sit? Is it better horizontal vs vertical?

Re: Showman Amp
There will be some difference in the sound with the cab placed vertically vs. horizontally. The brackets holding the head in place are needed because of the tilt-back feature, for which the lower CG with the speaker horizontal makes a more stable arrangement.
