Re: The Much Anticipated (?) Bluesmaster Build Thread
Going over some details before doing anything else on the amp today and had a question: Given that I’m building a 50w BM, should I be using the 8ohm tap for my GNFB? I did this on my 102 because of the change from 100w to 50w - so I’m thinking this principle would apply here as well. Am I actually l...

Re: 3rd Gen ODS by FictitiousFuzz
Thank you and I’m glad my questions were helpful - it took me a long time to work up the courage to start asking, lol. This community of experts is so very generous and helpful to the new guys like us! I’ve learned so much on this site from these great folks and truly appreciate all the knowledge an...

Re: The Much Anticipated (?) Bluesmaster Build Thread
Got this done last week and forgot to post it. Made the boards myself with Martin’s plans. One “new” thing I tried was using two larger eyelets for the two cathode ground points on the board. I think they are 3.5mm-ish. Also, mounted the HRM using small nylon stand-offs and screws. Seems to work ok ...

Re: The Much Anticipated (?) Bluesmaster Build Thread
Been a busy last few days, but the house is quiet today and I’ve been plugging away. Even though my time to work on this amp has been limited, I’ve used the past few days to go back and re-read a few BM build threads just to keep the mental wheels turning. I always discover (subtle) things previousl...

Re: 3rd Gen ODS by FictitiousFuzz
Great build! Really interesting to see the whole process from design/drawings to the finished amp. Really well done

Re: 2nd Gen Build
Classic, seasoned iron, brown caps, Pihers - should sound great! Looking forward to hearing your thoughts about the sound. Great build Dan

Re: The Much Anticipated (?) Bluesmaster Build Thread
All connected up as listed a couple of posts ago. Assuming I got it right - that’s the relays done. I preset the pot on the PAB to 100k to start with. Not much left before it’s time to hang some transformers on this thing. Made all but one co-ax cable (probably do it tomorrow). My previous 2 builds ...

Re: The Much Anticipated (?) Bluesmaster Build Thread
Ahhhh… ok; now it makes sense, thanks Martin. I’ve compared the schematic, layout, and board plans exhaustively - even drawing out the three and comparing. I was wondering if the difference had to do with the relay power. It seemed like the only answer - but again my lack of knowledge prevented me f...

Re: The Much Anticipated (?) Bluesmaster Build Thread
Ok, got some time today to hopefully wrap up the relay wiring. Based on my previous questions about the OD relay and Martin’s super helpful explanation along with looking at the schematic and layout - I think the relay wiring is as follows: COM1 - Loop send tip & return switch (orange and blue on th...

Ha! Great minds Glenn!

Re: The Much Anticipated (?) Bluesmaster Build Thread
Got up this morning feeling like I wanted to do something with this build that I actually understand, so I spent the morning making the cabinet. A little detail that I started putting in my cabs about a year ago are 4” long 1/4x1/4” “sliders” for the chassis. This way I can slide the chassis in to w...

Re: The Much Anticipated (?) Bluesmaster Build Thread
Thanks Martin, This build is proving a little more challenging than I expected just because of the different references, but I’ll get it. Apologies for creating my own miscommunication with the 47pf - definitely my goof up, lol. I read the mid cap as a 39pf 1kv and the V1b cap as a 50pf 1kv. Guess I...

Re: The Much Anticipated (?) Bluesmaster Build Thread
Thanks Martin! I don’t think I would have made the correlation regarding the section outputs without some help. I’m able to keep the layout, board plans, and schematic in perspective most of the time; but I do get turned around here and there. My ability to translate the schematic doesn’t seem to be...
