Guitar Shop Sales BS?

To answer the OP question, YES, this is sales guy BS. The Deluxe & Deville are two different amps. One is designed to output 40 watts, the other 60. The circuits are similar but the supply voltages are different as I noted already. No way will any load change affect the output wattage to any significant degree. Whatever differences are heard are the result of different speakers/quantities/cabinets. Give it a rest.

 

Yes, the amps are the same but their power supplies are different.

Like a particular car model available with different engines.

 

Thanks! (If you have the extra secondary) this seems superior to a manual impedance selector switch or just living with an impedance mismatch in the vintage style.

But, really only 100% effective *IF* the owner plugs in the correct impedance external speaker.

Using a single 8Ω external speaker is correct, but if the external cabinet is 2-speakers, the odds are they're two 8Ω speakers in parallel, which is a 4Ω load...unless, it's two 4Ω speakers wired in series, which would be correct. Thus, 50% chance of screwing up.

 

Yep - like trying to turn your 327 into a 427 by changing to a non-restrictive air cleaner.

 

Once in a store playing an inexpensive but nice amp a GC sales person approached and shared he had the same amp but sold it because he needed a louder one. I said why not just daisy chain it and run a cable from the 2nd input first amp into the 1st input second amp. For the money it was a cheaper option. Young guys eyes got real wide and and he shared something about galactic destruction and a tear in the space time continuum.

 

Instead of "amp" don't you mean "channel"? Otherwise he's still buying another amp - not cheaper.
And besides, daisy chaining channels won't increase the amp's total volume. That's determined by the output section and available power. That's why the young guy's brain black-holed on you.

 

At various times in my illustrious career, I have done music store retail sales.
I have about 12 years of music store experience.
I have witnessed a few of my co-workers BS-ing and misinforming customers.
Some of the BS-ing was the result of ignorance, some arrogance, and some manipulation.
Not much "vetting" of these employees was done by employers, especially in "big box" type stores.
I found it less common in Mom & Pop stores.
When shopping for gear, do the homework yourself.

 

Two things....that windmilling action in and of itself does not have to guarantee that the pick is hitting those strings as hard as one might think. Player control can still have some say in what the pick does at the strings. And....P.T. always used big amps....the HiWatts in particular yielded big cleans.
Suggestion.....try a 5751 in V1. It will give you better control over what goes on there and will also make the overdrive functions more musical, ime.

 

Well as the name implies his job is to sell, not to educate the customer.

If you plugged a cab into a vintage amp and halve the impedance on the output transformer you could in theory liberate more power. But Wally is on the money. There are other limits - tubes and power supplies don't respond linearly to extra current demand (if you can't increase voltage, you'd need extra current to ramp power up). Doubling speaker area does give more perceived volume but sorta negates the advantage of a combo. The o/t can also reduce or throttle power. There was a series of DIY Playmaster valve amps here in Oz the 60s using topcap 6DQ6 tubes, same P/t and the 40 watter used 6DQ6As while the 60 watter used 6DQ6Bs and a different o/t. That was Electronics Australia projects and they were very clean amps.

However I'd also concur - one bandmate has a 40watt Blues Deluxe and another in another band a Hotrod Deluxe single speaker that are both five-year yo so I presume 40 watts. Both are way, way loud on clean channel on about '3'. I've never heard breakup from either at loud drummer levels. Gotta be something wrong with that amp.

 

tooTone, that amp is likely biased very cool.....ime, when those amps are biased to at least 50% of max plate dissipation, they warm up and are much richer harmonically.

 

While the science behind how many watts it takes to be louder is solid, it misses the fact that what you're looking for is more clean headroom, not more volume.

Running power tubes at higher voltage increases clean headroom more noticeably than volume, so you could turn up the clean channel to a noticeably higher volume before it distorts.

Running a pair of 6L6 at 425v gives little clean headroom (compared to 6L6 at 460v), and it's possible that the Deluxe doesn't even produce 40w "at clipping", or when it just starts to distort.

 

To put my post context, I play in a 6 piece band. I run my HR Deville 2x12 (that has a low gain V1 tube) at appx 1.5 for practice and maybe a teeny smidge higher for gigs. It's freaking loud. I can push it to hairiness with a boost and humbuckers.
