50 Watt HRM

Post by dcribbs1412 »

Nothin new just posting bad pic of some crappy wiring of
my second redo of my original Dlite
Converted Dlite to HRM
added buffered loop...and it's fairly quiet
KT77 tubes
So far I'm kinda likin this circuit, decent cleans that will feedback
and I think I can learn to manage the OD+PAB.
In a small BNote 1x12 cab with old 12-65 celestion she can be an uptight little screamer.
Gonna run it for awhile and see.

Darin my quad 6V6 HRM is a screamer as well. I implemented an HRM tone stack lift and it will just take off. If I could do it all over again, I would have put the HRM tone stack lift on the PAB relay.

Nice dude! I'm building out a D'Lite kit for a client. Any suggestions for general mods/enhancements to the D'Lite platform? I'm gonna add a PI AC adjustment trimmer, 120/220V switch (international PT), RF Choke mod, and a send/return out to a DLator. Any other *must haves* ?

A bunch of folks have had good luck, myself included modding the BN D'lite to the 50W tweaked version. I set mine up for jazz runs and it has slightly heavier filtering, 60W OT and about 465V on the plates. I do prefer the choke over the power resistor.

Thanks TM!

Client is predominantly a jazz player and uses a 335. He also plays a Gretsch with a swing/country ensemble. This amp will be running the international version PT and a 2x6L6 OT (both supplied by BN). Good to know about the choke vs. resistor. Will probably go with the choke full time then (one less switch). Better ripple rejection anyway.

I gotta ask "put the HRM tone stack lift on the PAB relay"
any tips you can share?
Colossal
thanks
Agree with TM
the 50 watt with choke,
relays(PAB,OD,Mid Boost) and a internal(external loop) make this is a versatile grab-n-go little monster.
I like the BN PT fine never warmed up to the dual OT...YMMV

Excellent, thanks Darin. This amp will have a trio of relays as well. I can't recall if the OT is dual or single primary. I *think* it is 4k3 (Bassman) specs.

Darin, I would wired it without the conventional PAB and used the PAB relay to lift the HRM tone stack.

You might be right..
looking back at the BN site
I have the smaller 22/33 dlite OT
you might have larger 44w set with 4.4K & 6.2K
looking forward to your build posts...

TM
about the HRM stack lift
are you just lifting the ground off the OD tone stack with a relay?

Darin,

The OT I have on hand (sent by Moss) is a single primary (presumably 4k3 or 4k4). Looks like a Mag Components (end bells are scraped). 4/8/16R secondaries.

Darin, it's push/pull pot on the mid pot, pull it to lift the HRM.

Cool...should make for a great amp
BTW which style circuit are you doing?...ie 102,183

Beautiful build TM
not sure I remember this. Nice....HRM on the preboard and the NOS candy...snubbers on V2?
I'll do a search on this build and backtrack

Well, that's a good question and the short/dumb answer would be the 'stock circuit' :lol: I could use some steering in this regard. The kit came to me partially assembled for complete rework. I had planned to build it stock but with a couple of the usual tweaks; PI trimmer, send/return jacks, etc. I am completely redoing the boards from scratch. The previous builder was a friend of the client and has built a few pedals but had NO idea whatsoever about assembly and lead dress. I should post a photo of the boards although it would be rude/mean to mock his effort. They are hilarious and would make a sticky of what not to do.

So any suggestions for a circuit would be appreciated. The player is primarily jazz and plays a 335. So I know he is looking for clarity, deep, articulate lows sans the boomy/blatty mud where you don't quite get the midrange content you want, and of course the sonorous, blooming overdrive that is distortion without distortion.

Thanks, in advance. Sorry to thread jack!

All the best,
Dave

Hi Dave
I'm sure you may get a lot of different suggestions.
But from my very limited experience
You might want to start with the 3rd Gen or 70's style circuit..low plates
and go from there...a little work and you can convert it to a high plate
102, 183 or even a BM.
Pretty sure you'll be able to get decent cleans from most of these circuits with a 335...matching the OD may be another story.
I think it might have to do with the player and how he/she gets to know how to "play the amp" whichever circuit you build. Again just my suggestion.

Darin
