Ha! Great minds Glenn!

Seemed like a simple solution. Makes life easier.

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...

Great progress Matt! Looks fantastic, probably sounds even better

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...

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...

Also looking ahead to the relay wiring; just wanted to ask a couple of clarification-type questions regarding the “OD Relay Separate Masters HRM, Bluesmaster” board plans, especially since the connections are a little different than the layout: Cl = “clean” i.e. Cl Vol Wiper is the volume pot next t...

Ok, good - thanks Martin! The front is my preference also - mainly because I didn’t grind the finish off under the terminal strip at V1, and the terminal strip screw eyes just don’t look as beefy as a real grounding lug (I used mini strips because I already had them). I have plenty of room by the ja...

Today’s trivial question: Been meaning to ask about the shielded cable from the input jack to V1. In this amp, I see that HAD grounded it at the terminal strip. Is there any technical reason he chose that location vs. the lugs up by the jack? Does it make any difference - ground is ground, right (ex...

Understood, thanks Martin. That’s what I was thinking - but wanted to be certain just in case.

Got a Mouser box Friday evening and kind of just went bananas since then. That Triad 12v transformer dropped right in, got my small boards buttoned up and installed and got the tube sockets “decorated”. And I still managed to get about 4 hours of yard work done yesterday as well, so my better half c...

Glenn, That chopstick trick is actually what I’ve been using as a trimmer adjuster. I have a long one and a short one. They work great, and I can say I made them myself. I make sure anything I stick in the chassis when it’s running is non-conductive. Learned that one at about age 5 when I plugged a ...

Hey, that’s helpful Martin! Been searching on and off today and had a few “maybes” - but this saves me some energy, lol.

How does the 25 turn thing work? Just better fine tuning due to the multiple turns?

Thanks and very much appreciated!

Understood. I’ve got a conversion “map” for the Hoffman boards that makes using your plans easy. Just thinking through the differences to try and anticipate any traffic jams. Just to be sure; I’m using the “Separate Masters HRM, Bluesmaster” connections, correct? Every time I look at the layout then...

I’ll do that Martin👍 Question about the layout: it looks to me like the relay system is not wired the same way your boards are; but it seems like the mdroberts schematic is closer to yours (from what I can tell - can’t figure out the relay board Com points on the schem). Am I correct or am I misinte...

Thanks Martin! I’m pretty happy with how the PS worked out and it wasn’t difficult to do at all. Your plans were easy to follow and everything fit perfectly. It’s pretty amazing how there’s so much more selection for way less cost in radial and snap in components; and I agree that it still has the D...
