inspiredsports,

That's sweet too!

Could you elaborate a little on your build? You can't just tease us with one pic . . . more pics please!

Thumbs-up!

mrbigbluelight

That is ........ just ......... ............... ............... :eek:

Two pics in particular, IMO, should be reported as ****:

Pic #7 in Post 179.

Pic #7 in Post 180.


Pic #7 in Post 180 .......... deserves to be made into a poster .... or a print .... or an oil painting ....... Straight up, that is just downright nasty !!

Excellent work. If the sound is up to half the appearance, then the gods have smiled on you. Well done.

I too love the nameplate, it looks freaking awesome!

Oh, that's not me, but I would sure like to own is as my primary guitar amp :biggrin:

I have some old tube gear and get great help at the antiqueradios.com forum. This 56-tube brute was built many years ago by a longtime member there who I believe plays out and uses it as his keyboard amp!

There are hundreds of posts in his thread about it at http://antiqueradios.com/forums/viewtopic.php?t=106988

Thanks for the link - very informational site. Another forum on my daily visit list.

56-tube!!! Imagine the power . . . and having to trouble-shoot to find a failing tube.:biggrin:

Not to mislead, it's only a 100 WRMS unit, (much less power than John's beautiful project). The antiqueradio.com builder is just anal about controlling, monitoring and diagnosing things on the fly (like tube failure which causes it to auto-shutdown) :biggrin:

I hope to see you and those amps during PF11 :biggrin:

Here are a few pictures of the bottom plate amd the wood side panels. They are both nekkid for now. The bottom plate will have a screen over the ventilation holes to prevent things from getting inside.

it is a good looking amp for sure, But do not just pay attention on the outside. I saw the wiring in the inside and it is not as neat as it should be. all the time when you deal with AC you should twist those wire very neat and close to the chassis. do not leave them "floating". just my 2cents.

I'm sorry but when you do an amplifier of this kind, you can be as anal as your are on him on yourself.

Until then? Kindly shut the ____ up.

All due respect, which is none.

They are nowhere near the point that I need to be concerned about that, as the insides are very much a work in progress. When you have the balls to put your money and time where your mouth is, then start your own thread. You can keep the two cents...

Really? Wow! Perhaps you'd like to give me some advice on my newly rebuilt 50 year old Eico ST-70 which sounds spectacular despite it's hideous wiring job. Only look if you can handle looking at the dog's regurgitated breakfast.

John, your amps look spectacular. Period.

nooshinjohn

Thanks to all for the kind words. I am madly in love with these things as you can tell. I am still waiting for the transformers and the updated schematics from Bob so that I can complete them. I hope that they will be ready by late spring or early summer.

Thanks for the link. I might take back the troll comment but your earlier comments about John's amps were definitely bordering on or across the line rude. Just saying.

John, sorry for derailing your thread a little here. Please resume regularly scheduled thread commenting.

Willy, hope your leg feels better soon.

Those are some gorgeous looking amps John. I hope I can get a chance to hear them sometime.

I will ask this only once... please stop coming into this thread for the sole purpose of being an asshat:mad:.
This project was undertaken with the idea of doing something that I have never seen done before and making it a reality. The choice of material(granite) was made because of it's elegant appearance, and resistance to vibrations. The bias of the tubes will be done automatically by an internal circuit inside the amp.

The comments you made about the wiring earlier in the thread will be addressed when the work is completed later, and will look like this when completed...

You smelled correctly...

Now please, lets get back to our regular program.

Poee7R

He's a troll because he recommended a clean internal build?

Looks like an opinion to me. Guess if you cant handle someone's opinion, dont post a public thread?

Best not to include the spammers link when you quote their posts. The mods delete their original, but your quoting it under your name (post #166) keeps the link "alive".

inspiredsports

Those are absolutely beautiful amps. You should be mighty proud that you are able to pull this off. I hope I can muster the courage to try something like it someday.

I could knock down a hundred year-old oak tree with the woody I'm packin right now. Awesome.

:eek:speaking of space heaters, I am disgusted with myself for buying BOSE 301,s 7-8 years ago, now that they are in a storage room, I keep on thinking maybe I could put them in the fireplace and heat the room on a cold evening.

nooshinjohn

Thanks guys... The wife has made what I feel is an honestly good suggestion about the side panels. Her idea is to fill the sides with brushed aluminum instead of wood. Her thought is that with the brightwork around the tube bases and the trim band around the transformer covers, that the wood looks to busy and out of place. She also noted that other companies like Rogue(not by name) use brushed aluminum as accent pieces and she loves the way the material looks. She also said that it would tie in to the more contemporary look I have been going after, and then said "and besides, I have not seen any of your other gear that Bob designed using wood."

After caring of the wood she gave me when talking my language , I told her that I would give it a try. What say you guys?

Fongolio

Do what your wife says. Not only does she make good sense but when she tires of looking at those behemoths taking up so much space you can remind her that she helped design them. Always always work with WAF is my motto.

Looking good, now ask Bob ever so nicely, you really need some iron.

Smart lady.
