100W HRM in the BluesMaster Style?

If I get time I'll draw in the wire routing

I've reposted the draft layout with a recifier board based on what Funk ships with his chassis kit...

I will be updating the schematic to match this newer bias circuit.

Still lots of wiring/etc to do but getting closer.

Mark,

So far, it looks great!

I hope you intend to post a VISIO version.

Thanks BobW,

I made some progress so I've uploaded an updated version, but there's still lots to do.

I will be glad to post the Visio once I feel it is 'complete' so we don't propagate too many errors...

EDIT: Changed the mid-switch and to align with the layout.

Hi,
Attached is Version 9 of the schematic...
In this version there is a big hole where the D'lator used to be! I have given up trying to fit it into the chassis... I even went as far as doing a miniboard layout for it, but mechanically that was too tight a squeeze. Left in an 'FX Bypass Relay' and perhaps a JFET loop could be shoe-horned in place.
Also changed in this version is the bias supply details to match the Funk pre-punched board and the layout that is in development.
Speaking of the layout, some other minor changes (like PI tube triode order, FET Jack, Coax indicators, etc.) have been done to match the layout requirements.

I had space issues too with my inboard Dlator. Ended up using a 2 tier board for the PI the input side On the main board with the output on the 2nd story so to speak... freed up enough room for the d lator. Also used a little board between V3 & V4 (PI) ...

TT

I didn't think of that! Good ideas.

I tried to make a miniboard with all the components, jacks and direct connections to each pin on the tube for minimum footprint on the chassis... I made it so the jacks mount on the underside and lift the board up off of centre to clear the main board (see attached)... but it will protrude into the HRM!

Sigh. I think I'd like a wider chassis.

Here is a rough bill-of-materials kicked out by the schematic v9... Time to check off the components.

Anyone have any comments on the schematic or the BoM? I'd like to start filling in some details (i.e. Mouser P/N) on the BoM.

I hate to give up on the D-lator.... I know it's a tight fit, but there's a bunch of smart people on this forum and we ought to be able to get it in.

Cheers, Mike

I'm with you on this one Mike. I was thinking of mounting a 4th 12AX7 as per the mock-up in the photo below. It's has been suggested that the D-Lator board might fit in if piggy-backed over the main board sort of like the HRM board (Since it's a tight fit and probably not a great idea to cover the tubes with another little board).

Another option I'm thinking about is to do a FET dumbleator. I have some concerns about the Gary and Mark's Kleinulator design, but the concept might be worth pursueing. With this approach, I'd mount the Send and Return jacks right on the effects loop PCB and tuck it in rearof the chassis.

If you build a stand alone one you can use it with any amp.

Ah - but I don't want a stand-alone one. I want an integrated one! I want everything to look clean. Not a bunch of boxes and wires. And I want to have my effects loop on the same foot pedal as the other amp controls. I want a challenge dammit!!

BTW, I did not credit you for the original photo that I hacked for that tube placement mockup. Thanks!!

Hey All,

I've taken the Bill of Materials that Mark worked so hard to produce and added in some Mouser codes. I do not have a source for the 250k Audio taper pots so I've left them blank. Also, I'm not so sure the trimmer pots will fit Funks board.

Any suggestions?

Cheers, Mike

Buggers! This part number does not appear on their catalogue.

Thanks for the info heisthl.
