Finding the right ohms for a Vibrolux
PostPosted:Wed Apr 02, 2014 2:32 pm
Well I wasn't really shopping for one (just got rid of my 73 twin) but it was too good of a deal to let pass by. I watched a vintage Vibrolux come down by $100 every few days on CL and picked it up for a song. Turns out its a 73.
It has a the sweetest vintage G10-60 Rola Celestrion's (sliver) in it which sound amazing - but they are 15 ohms each so its the wrong impedance for the amp. I'm looking for a 4 ohm load and getting a 7.5 ohm load.
I've got a 1x12 JBL ext cab with an 8 ohm E120. If I simply run this out of the ext speaker jack am I then giving my amp close to the correct load - assuming I also use the Rola's.
Good news is I already have a 2x12 JBL 4 ohm cab, but that's a bit much to lug around.
My trusted amp tech says I'll be fne at low living room volumes with the Rola's but will damage the transformers if I push them at a gig.
Peace,
James
