Just as the title states, how would i go about it? The amp itself is rated at 8 ohms, no external jack, i would like to add one to power A 2x12 that is also 8 ohms. I know there is a way that will allow me to connect the 2x12 but will disable the internal speaker. So how would i go about this.

disconnect the speaker cable from the internal speake and use that to wire your 212. to get the 212 work like its supposed to, youd have to connect an 8ohm power resistor(of appropriate wattage) in parallel to the speakers.

EDIT: had the wrong diagram. Fixed.

If the amp powers 8 ohms and the 212 is 8 ohms, you don't need resistors (parallelling an 8 ohm resistor to an 8 ohm cab will make a 4 ohm load, basically).

Here's how to wire the jack.

I put a jack in between the amp and the speaker so I could switch easily from the internal speaker to an external cab:



.

Remove V1 & V6. Put the 12AX7 from V1 into V6 and leave V1 empty. Try the vibrato channel.

That's what TS is trying to do.

I put another jack on my old Frontman 25R so I can plug other amps into its speaker (mostly meant for my Radio Champ, as its speakers suck pretty hard). The speaker in my Frontman sounds pretty damn good for being a stock practice amp part.
