Re: Starting to populate the chassis....
Now for my criticism to you guys. I'm building a #124 100watt head. Looking forward to having it work, I hope I get it to work. Maybe not the best choice but I didn't want to build a kit. I wanted to pick and choose my components, make mistakes along the way. That's how we learn, make a mistake and...

Re: Bluesmaster HRM question:
Yes correct, and 250k makes life easier for finding a bass sweet spot.Raoul Duke wrote: ↑Wed Apr 10, 2024 1:16 pm Thanks Erwin!
So most BM/HRM circuits’ optimal bass adjustment setting is under 250k then based on what I’m reading. Is that fairly consistent with your experience and impressions of others’ builds?
Thanks again!

Re: Bluesmaster HRM question:
Trying to understand the “mega boost”/PAB in this amp. I understand that there’s some variation based on the individual amp - so the first question is: 1. Is PAB the same as “mega boost”? If not - what is the difference? Is it something unique not in the layout or schematic? For the FET: layout loo...

Re: SSS CF Driver Compression Questions
Those cathodes have a connection to the LNFB loops. Otherwise the LNFB loops would be shunted to ground.I see a schematic of #002 with added 100R resisters. Can anyone explain what those are going for?

Re: SSS CF Driver Compression Questions
A part of the compression is coming from the LNFB loops. Especially when you drive the first volume pot a little more.
Not all SSS are the same as are the LNFB loops.
Which one do you have?

Re: Bluesmaster HRM question:
I was talking about the front panel pots; I hadn’t seen any real variation on the HRM board. I’m on a quest to better understand how the composition of the primary tone stack lays the foundation for an amp’s character and saw all the variations in the Bluesmaster; so I thought it might be a good le...

Re: Bluesmaster HRM question:
The Bluesmaster tonestack is not a skyliner nor a classic tonestack. While a skyliner might be low mid heavy, the Bluesmaster might be low bass heavy. Some might shave off some bass pot value to get a more usually pot swipe setting. Paying attention to the first tube voltages is imo the best solutio...

Re: 2nd gen ODS with Erwin chassis.
Really enjoying this amp. In the meantime I have made a headshell and combo cab (just need to make a front baffle to complete). Details of the circuit to date to follow, including a master (hope Erwin doesn’t mind me drilling his lovely chassis :? ). Lovely and great looking amp. That master is sim...

Re: Starting to populate the chassis....
Hi Brian, we are ok. I was just flabbergasted, but as you pointed out it was just to be sure. I'm ok with that.
