In general the PAB makes both amps more aggressive. I like both modes, unlike some of the other folks here who feel the HRM only sounds right with PAB on.

So the answer is yes, both modes are more aggressive on the non-HRM but trust me, the HRM is plenty aggressive.

Check out the recordings on my band's website below. Straight HRM, no additional effects.

that is what I have found to be the case also with my 50 watt HRM , I just got the impression that when people say that the HRM is less agressive they are talkin about the amp with pab engaged which is how most are tuned to opperate compared to the non boosted non HRM

also the low end holds together better in the HRM and note seperation seem's better also [IMHO] but that said no clear winner for me,ya need one of each

Who'd a thunk that?

I has some interesting departures from a Dumble circuit such as the plate and cathode treatment in the preamp.

The pregain pot on the cathode is interesting.

Looks like this amp uses a WZ34 Copper Cap rectifier.
I would much rather just use discrete diodes for that purpose.

Too bad they didn't keep it truer to the ODS Design but I suppose that's the way that goes.

Did you build it stock before modding it or did you have your sights on a HRM Dumble when you started it?

So with no caps (because I want to use 6PS) , no copper cap, no tubes
it came to $605.

Not bad as long as the parts are decent.

Isn't it true that they improved the quality of the small parts like jacks and pilot lights, etc?
I sort of like how they use the copper cap, it gives you the ability to adjust the voltage drop and sag really easily and quickly, i bought a copper cap that has the qualities of a true solid state rectifier as im not a huge fan of sag. As for the build i'm following their basic layout but im changing alot of the values, especially in the tone stack. My amp isnt really a dumble "clone" it's more of a dumble based amp so i'm intentionally not using exact dumble values. If my ears like it im happy :D

Their parts are pretty good, i didnt like the solid core wire they sent with the amp as it's a bit too fragile. The chassis is great quality though, nice and thick. The sides are bent and are not welded like most chassis (welding weakens aluminum though) and it's perfectly stable as is. The pots are pretty generic, they dont have anything stamped on the back, but overall seem like decent quality. Theres no effects loop but they can be added easily, keep it passive because of the lack of space. Also youre probably going to use a different board, so it wont be as crowded, the board supplied is not designed for 6PS caps which are pretty large generally
It's true i've lost my marbles and i cant remember where i put them

Whoa!

Old thread.

Is JD0x0 still around?

I wonder what the dimensions of that Halle chassis is?

I am also desiding what i want to build. I was leaning toward a Low Plate Classic 124 or 2nd Generation but after reading the great review of Jelle's HRM I am not so sure. The Lance Keltner You Tube of a Bludotone makes the choosing very hard. Now i understand why so many members build more than one amp

Here's a link to their chassis dimensions: http://www.webervst.com/chassis/

As far as the original question goes...I've only played a Ceriatone HRM BM and a clone I built as close as possible to a 124 skyliner. I prefered the BM voice more but they really are different beasts. The BM had more bark and a more controlled/compressed voice from clean to OD. The 124 had some pristine cleans and the OD was wild. Overall the 124 had a more open voice. Pretty soon I hope to scratch build a BM as I sold the Ctone.

I hate to pick favorites, but my buds all seem to gravitate toward the high-plate Skyliner and BM amps.

Same here. That Lance Keltner vid sounds just what I an looking for. Only thing he doesn't demonstrate enough are the cleans. I'm looking for a clean that will take pedals well.

Bludotone

What do you suppose that Bludotone is set up like.... high plate? Sounds great.

Keltners Bludo is a 2rd Generation hybrid "classic", 100w with 6L6's, and added presence control, Ftsw'able FET via relay, Fet Level control on the front panel, and separate Master Volume's for the Clean and Overdrive.

JBorders (Jason) just uploaded a Layout of the same config. as Keltners Bludo.

Greg, just to avoid misunderstandings concerning the term 2nd Generation hybrid "classic":

This layout of JBorders shows a 2nd generation "pre-classic" tone stack (exception: "mid" switch instead of the usual "deep" switch) and the "funky OD entrance": https://tubeamparchive.com/viewtopic.php?t=12870

The transition generation and 4th generation amps with a "classic" tone stack and a "standard" OD circuit (with trim pot and snubbers) are rather different beasts - at least AFAIK: https://tubeamparchive.com/viewtopic.php?t=12872

Cheers,

Max

"Not to be a spoil sport, but the Halle isn't a Dumble clone, not even close. "

I agree with that.It's not worth the effort if you want a D clone amp.
Crystal latice or vacuum,that is the question.

I am gathering parts to build Jason's hybrid layout as well.
I too heard the Keltner video on youtube and was hooked.

I will report back with progress when I get going (Mostly waiting on silver CE chassis....)
