A good old fashioned bulb with a bit of wire that gives off light when it gets hot

General Lighting Service Lamp.
Electricians have funny names for things. Why oh why we have to call bulbs lamps is beyond me.

A standard tungsten/argon bulb.

Energy efficiency laws have kicked in, so you can no longer buy GLS.
It's kind of stupid really.
They banned the higher power ones first (for incandescent the higher the power the more efficient).
Now they allow modified halogens in low power (halogens are only efficient in high power).
Or CFL (compact flourescent lamp).
CFL are not that efficient and as no-one has hazardous disposal at home it will involve a LOT of mercury being released in to the environment.

High power lamps should be fluorescent (but they have banned them, so only allowed the smaller less efficient ones), or LED (which are just brilliant, poor pun sorry).

Yet do they recommend the LED, do they !"$.

It is silly one of my friends had to exchange hundreds of 6' florescent (which are really efficient) for 5' as they use less power (but produce even less light).
So basically a supermarket had to spend tens of thousands to make their lighting less efficient to comply with efficiency laws! Absolutely ridiculous, but at least it keeps my friends busy.

I have some GREAT issuses with those "intelligent" people who made it illegal to produce and use GLS-lamps.
For what is it we have got instead of theese harmless incadence lamps?

Lamps filled with mercury, wich demands special waste treatment with more trucks driving around for to pick them up whenever those lamps is thrown away.
Possibly more mercuyr in the nature due to most peoples rather careless handling of such lamps, intentionally or not.
And here in the COLD north (Some minus 10C here now) the energy saving lamps have trouble lighting up where mounted outdoors, and the missing heat from the incadence lamps inside has to be provided by more power via the radiators anyway.

NO real power saving,
HEAVIER load to the enviroment.

Thanks a lot Enviromentalists behind this IDIOTIC banning of incedence lamps.

For me the only toruble is the fact that there is already much more difficult to get scalelamps for all vintage radios with incadence lamps to lighten up scales and indicators.
And LED is a rather poor replacement.

Well, there went a lot of steam.

For cold temps LEDs are even better, the colder you run them, the more efficient they get.

There is a HUGE difference in efficiencies though.

You need to be buying cutting edge.

The old luxeon 3W LEDs put out about 90 lumens and were very fragile.
The current Cree 3W put out over 500 and are reliable.

Buy some Cree LEDs, buy a separate driver (get a good one) and you have an efficient powerful light.

To get back on topic.

The RB-993 is now working fine (and will hopefully stay that way).

The right channel of the RB-991 is silent....

What things can I be checking with only a multimeter?

loss of signal is going to be hard to find with just a multimeter a signal tracer and tone generator would certainly help...
