The chassis are here

That's fantastic!  EXCELLENT improvements.

Thanks, Tubenit

Thanks Jeff
If you guys can think of any others, now is the time to do it

If you guys can think of any others, now is the time to do it

Looks more "universal" now but IMHO I don't quite get why smaller EL84 holes aren't utilized first? Would it not be easy to open the holes up for octals if one would want to got that route?

I always seem to have a need for at least one switch on the front panel for purposes of optional biasing, bypassing, cascading, etc...
 
The only thing missing now is the bottle opener on the back panel and a hook for a shoe horn for anyone that fills all those holes with pots & sockets? 

[EL34]

The average guy cannot make big holes in chassis

Not sure how you would even do it when there is already a big hole there to begin with
Hole saws rely on using a small pilot bit to keep them centered

A greenlee hole punch that large is expensive

It's much easier to block off the 8 pin holes with my adapters
They work great and don't cost much



And also, I am seeing that more people are building with 6V6's than EL84's

[jojokeo]

You just use a step bit but I understand where you're coming from. So in that light I think you should make one more adapter in case one would want to use EL90/6BQ5 or other 7-pin power tubes?

[EL34]

I don't make the adapters
I get them from mojo
Those 3 are the only adapters they make

Not sure if anyone out there makes such a thing?


Anywho, this helps people that do not have fabricating skills and there are allot more of those people than those that do have fabricating skills

6bq5 is noval.


6aq5 is 7 pin.

^ = fit not verified, however mfg. end bell window cut-out data and hole spacing data correlate.
+ = fit not verified, however, same part family as one that fit, so should fit.
* = minor fitment may be required such as slight enlarging of mtg. holes and/or end bell window.

if an end bell does not fit, but the mounting holes do, then you have the option of removing the end bell. be careful removing the nuts
that secure the end bell. check beforehand as they may be varnished in place: if that's the case, then removing the end bell wouldn't be recommended.

Pete, you do 99 now do 100 

Why not a list of all circuit that can fit on the chassis and of Doug's board that can fit there ?

Wow, thats cool Pete, thanks

Check this thread for an opportunity to grab a new pine head cab designed for the new chassis.
Limited time run, only available whilst I'm in the mood.
Meant for the thrifty builder.

Oh cool,
Love to see one with the front panel on


And to go along with your cabinet deal, I have the chassis on sale for $38 right now on this page
http://hoffmanamps.com/MyStore/catalog/Chassis.htm

That would be a chassis and a cabinet for under $100
