Complete Bluesmaster Layout

[talbany]

Hello All

Onward and upward.. Here is a layout of a Bluesmaster HRM...
Since this particular amp was still gooped some of the info I needed to keep this accurate such as types of the parts used in some areas is just not possible at this time..So this is a sort of collage of info taken through various sources but should make for a good starting point..Please look over the layout and let me know if you spot something you think is not accurate or wish to add.. By all means!!
This is revision 1.. If you save it now be sure to stop by and look for future revisions if any should arise..Special thanks to Scott, mdroberts1234, who originally started the layout and Ultra Hooked who I copped the PS and HRM boards from(he does awesome work) and all those kind enough to PM me info they had.. It's all good..Enjoy

BTW.. If you use a loop on this amp you may want to raise the master bright to 68pf.. thought I'd mention.. Also this has the Mega-boost like in the original.. If you want a more subtle boost lift the bottom of the mid pot 68K instead of straight to ground..

Is this one supposed to represent a specific serial number, like 199? The Bluesmaster stuff I've collected shows a 47pF cap across the 470K in the pre-OD trimmer network.

Thanks Guy's Glad it helped!!
Hi Jaysg

The 47pf was a bit of a conflict for me as I have heard conflicting results from using the cap in the BM.. Most I've talked with prefer it without the cap I know I do.. I can't really say for certain all the Bluesmasters had them.. Perhaps Scott could chime in here if they did in fact exist on the BM I'll be glad to revise it..

I removed the 47pf cap also and I prefer it without. There's not a whole lot of difference @ low volumes but it is noticeable and more revealing without it. More open sounding IMO.

Small niggle. The pilot light is not wired right on the terminal strip.

[talbany]

Thanks Tom.. Other side of the diode..Rev 2 up

I also added the 47pf bypass cap on the OD entrance labeled optional

Pardon my ignorance - what does "2-35" on the treble pot mean?
