I am reading and listening to anatech, rdf, latala, wrenchone, djk, poobah, burnedfinger, quasi, mr T, planet10, tubelab...

and everybody else who takes the time to post. I hope you all come out to the polls. It is your right as a DIY AUDIO Citizen!

Turning up the fun meter some more,

Shawn.

This design could be a virtual "Shoe-In" for the old Crown DC300A enclosure.

Hi Shawn,
At least no one has voted to use it as an anchor. So far it's lookinh like a restoration.

You know, you can always rebuild it later, but try to restore it first.

You looked too soon...

For me I would not! go the quasie route
While it is a credible design I dont feel it either restores the Crown or take amplifier design forward a single jot!!
You have relegated the Crown to that of a donor.
I would rather some one use me than consigne the Crown to that fate !
You have lost the current boosting facility if you go with Quasie.s design a most important Crown feature no offence intended Quasie
For me the real challenge would be to get the booster concept really working rather akin to the quad concept!

Restore it!

Quit worrying about the semi's... they are not blown? Use 'em.

Clean it... cap it... resistor it. Leave the battle scars too. Or go nuts and replate every thing. BTW... re-anodizing something is fraught with peril.

Borrow some speakers from Cal and punish bad people with it.

says who?

which parts need anodizing? the transistor heat sinks or the chasis?

inquiring minds want to know...

I think Shawn is wanting to improve the performance of this old horse. Use 'em? Nah, lose 'em. Use the nice shiny new parts and see if the original concept works better. Besides, some of those parts were running too hot over 30 years now. They are just waiting to take some other parts with them. Dodge that bullet.

Chris,

Sure... why not?

Auplater,

Spill it... I had some alum. window moldings for a Lamborghini re-anodized once. Let's just say I spent about a week with hammers and an English wheel to make new ones. I think they got the current per area thing screwed up... dunno... fried them though.

How do get the old stuff off?
