Direct Line Out for Marshall Class 5

[bluesmandan]

Hello all. Does anyone know if the C5 headphone out can be converted to a regular direct lineout? I'm thinking the internal dummy load and cut off switch can be bypassed, so that the internal speaker will work, and the headphone out could function as a lineout for plugging into a PA or other amplifier. Has anyone done anything like this? It would be a great option for larger gigs...

Anything you can dream up can pretty much be done with manipulation of electronic circuits. There are a ton of ways to the same exact thing with regard to my previous statement. It is usually just a matter of time, money, patience, skill/knowledge level, ect.

If you have at least some good tech skills or beyond, try this as a helpful resource for a starting point. It would be a good idea to get the schematic for the class 5 if you don't already have it.

Hope that helps.

Thanks, where can I get the schematic for the C5?

Just try browsing the web, someone on here might have it.

Hi Guys

The line output is simply a divided version of the speaker output - two resistors will suffice, or a resistor and a pot, or just a pot. You will want to EQ it for recording and most other purposes.

If you want a ground-isolated line out, use a small transformer such as the Hammond 109T or 109H. The secondary can be used as a balanced output via a TRS or XLR jack and 3-conductor cable. Either of these transformers can handle the full signal voltage at the C5 output. If you spend a bit more money, you can get a good mu-metal encased 1:1 line transformer from Sowter, Lundahl, Cinemag or Jensen.

Have fun

Yes I figured out how exactly to do this + more... See my posts on the NEW CLASS 5 VOLUME MOD for details...

Before you start messing around with any waranty degrading stuff, you could try to use software likes of Guitar Rig as power amp and speaker emulation.

I managed to do a fairly good emulation for my Lil' Elvis by tapping the signal from a pedal in the FX-loop.
I did a quick attempt on the VM, but that didn't really work out that well... but in all honesty... I didn't really give it a fair attempt though.
Requires some trying and failing.

A pedal in the FX loop can be used to kill the volume in to the power section, thus killing the amps output as well.

I wouldn't recommend any Master Volume nob/MOD but YES you can turn the Headphone OUT to a DI to slave to another AMP run direct to the board or whatever you want and this will not 'degrade your amp in any-way but instead vastly improve upon it's TONE and versatility... see my threads for all the details with more to come... Already shared how to get a MV for the headphone OUT now I am going to cover making a special DI/Slave/OUTPUT that can be used with this Volume/POT/MOD to give you a huge range of possibilities...also to be covered is how to add and External speaker Jack that can be used with or without the internal speaker....+++ more to come...
