NAD cheap and cheerful

Excuse the indoor phone pic.

E-Wave KS-5H and GC-110 cab.
5w, preamp has a 12AX7 and the power tube being an EL84
the cab has a 30w 10" Celestion Tube 10 so apparently pretty average or below, but fuck me it's loud and clear!

I wanted something for the bedroom and the Laney lc15 will go there and this probably get the main use, though I do need an attenuator for the loop, very touchy level and gain knobs go from naught to 100 so can't really get it as sensible as I need.


Anyone want to swap an attenuator for a digitech screamin' blues pedal?

Sarge

A little research suggests I can just install an Lpad in the cab, could it be that simple?

underdog

I used an Lpad with an Epi valve junior, it worked great. I housed it in a separate box so I could use it with other amps though.

Sarge

Ok cool, so should I go for a higher wattage? the speaker is 30w, so say 100w will be fine?

ICBM

Yes with that amp, but be careful with L-Pads. The standard "100W" ones you buy doesn't mean they will take 100W of electrical power, it means they can be used as the treble attenuator in a 100W music system, which was the original purpose. The actual electrical power they will take is more like about 20W I think, which also doesn't mean a cranked 20W electric guitar amp! A distorted amp can put out up to double the rated power.

Or to cut a long story short, safe with a 10W amp or less, but any more may be pushing it.

Sarge

Oh so it's the amp's wattage not the speaker's?
If I were to go this route, which would be best?
thanks for the valuable info :-)

ICBM

For that amp, the "100W" L-Pad will be plenty. Just don't run a much more powerful amp into the cab.

Sarge

Thanks very much @ICBM, much appreciated.

A loop attenuator is beer into water to build.

Surprised "our Rob " doesn't knock 'em out?

Dave.

Sarge

@ICBM do you have any of these 100w L-Pads to sell?
I've been looking around and the suitable spec ones are either out of stock or in the USA (or very very pricey)
or could you recommend somewhere to ghet one?

cheers!

ICBM

No, sorry. I've seen them on Ebay before but I don't know if there are any available just now.

Sarge

Ah no worries, I found one for £20 delivered with a facia.

Thanks again for your help!

Sarge

Well, stumbled at the first hurdle.
Can't get rhe back if the bastard cab off!
Tried levering it around the edges but it's sodding chipboard, about 1" thick.
Fuck fucking fucked off

Take out the jack plate and use the hole to pull the back off. If pulling by hand fails you may need to rig up some sort of jacking arrangement - it's not always easy but I've never had it fail.

If you lay the cabinet face down, put two pieces of wood on the edges of the sides (so they're not on the back) and another strong crossbar on them, across the cab over the jack plate hole, you should then be able to get a G-clamp into the hole and tighten it towards the crossbar so it pulls the back off. Sometimes you have to leave it a while and re-tighten it if it's really stuck.

23 hours later and I've prised it off, need a smoke!

@ICBM may I trouble you for a tad more advice?
Billy basic cab, input jack, + & - (red&black wires) straight to the speaker terminals, and tabs numbered 1.2.3. On the lpad..... So 2 wires and 3 lpad tabs, which goes where?

Sarge

All the diagrams I've found use a crossover, none match my 1x

Sarge

Ha, thanks for the removal tips, like the g clamp brace idea!

ICBM

I think 1 will be the common ground connection, 2 the output and 3 the input, but check the diagram.

If so, wire it like this:

Sarge

Will do, thanks bud.

Sarge

I'm not sure how to tell which is the common ground, the lpad is the monacor AT-62H if that helps?

Sarge

Again I have to profess my adoration for @ICBM. The man be a legend!

Thanks a lot man, now all I have to do is butcher a hole in the cabs back and mount this sucker!
