Klemt Echolette M100 tube amp

Hello,
[ I don't know if this thread belong to here (this is not a stompbox, but musicians like to use these amps like effects), so if not, mods please feel free to move it ]
I recently got a Klemt Echolette M100, but i am not sure how I should connect the output, and i wouldn't like to make a mistake : I want to use it as an effect (like a regular rack or pedal effect), not like a power amp with speakers.
I can't find the service manual, nor the operation manual for it...
Should I use the phone out din plug on the front for that usage ?
Can i safely use it without speakers (i have read on GS some people assume that it wasn't advised to do so) ?
Is there any way to use the jack sockets on the back to connect to a mixer desk instead of speakers (with impedance matching) ?

Hi
it seem the front DIN has an output for the mixer section, but could be used as insert (send return).
If I am right you could have your mixer output at a reasonable level, on pin 4, but the signal will still be hot for your amp input (11mV).
The other output on the back is a tape recorder connection, in and out, but the signal is hotter than on the front DIN.
The master volume control is post line out, which means you won't have a master pot for your mix, but you may be able to use this mixer without a load on the power amp output just by setting the volume to zero.

It has solid a state output stage so will be fine to run without speakers.
Even though it has an output transformer it has a very different output stage to a tube amp.

Thank you, DeltaFred.
One last question: If i wanted to use the main outputs (speakers), what kind of device should i use it with, to insert between the M100 and a mixer desk ?
Something like a impedance matcher, does it exist for such a use ? Like a DI box, but to insert between a power amp and a mixer desk...

I knew a guitarist in the Barnet area of North London around 1964-65 who used Echolette echo with an Echolette amp, and could play much Chet Atkins stuff - including Lullaby of Birdland!!

A good old powersoak lets you plus a small amp into a mixer, and even headphones.snk wrote: If i wanted to use the main outputs (speakers), what kind of device should i use it with, to insert between the M100 and a mixer desk ?

Otherwise most DI boxes can be placed post poweramp.

You can find several DI boxes which allow direct plug in the poweramp output, such as this one for example:

The Powersoak is an old power dissipator, simple resistor network, I still use it occasionaly to record straight from a Bassman head without speakers to not disturb the kids late at night

It's a SS output and does not need a load resistor,, all you need is a 10/1 ~ 20/1 voltage divider say a 100k series Resistor and a 10~20k pot and you have a variable line out. Actual resistance is not critical as long as it has 10~20/1 division.

Cool ,, just note the pot goes After the 220k resistor. It did not post the way I typed it.snk wrote:Wonderful !
Thank you, Phil
So speaker output connects to left of 220K and top of pot goes to right then pot to ground.

Hello,
I just found the time to drill an enclosure for it, and i was going to build the circuit, but i realized the pot is marked as 10K log : is it mandatory ?
I mean :
- will a low value (like 10K) have any incidence on the sound and roll the treble off (as opposed to something like 500K), or is it applicable only in other kind of circuits ?
- I checked, and i have only 50KA, 100KA and 500KA pots... Should I better order a 10KA pot, or should i adjust the resistor accordingly, in order to keep a 10/1 ~ 20/1 ratio ?
