cr 112 shorting out

[clamup1]

need to get a bigger power transformer?

i think that one of the original TIPs was flipped over and screwed to the heat sink. (i had to unscrew it to read it) but im not sure. i didnt take pics before i tore it apart.

i think im gonna park this thing for a while, this whole project has ticked me off

hey guys, the 127 was in backwards. now i need to find a piece of steel to attach the green wire to. i almost burned a hole in the carpet.

its kind of dissapointing that i cant make this a 212. ill save the other speaker for another amp i guess.
thanks for your help

actually you CAN make this a 2 12... Use something like Weber or Jensen mod low wattage 12s rated at 16 ohms in parallel
...you could also use 4 ohm speakers in series
just don;t use high wattage speakers...jensen mod 12-35s 16 ohm will probably work well.

however I think you'd be happier with the sound of something like a pair of weber 10F100t's  10" 15 watt speakers 16 ohm

but much more expensive.

You could probably get adequate volume out of a pair of Celestion Rocket 50s at 16 ohm too if you could find them.

i bought 2 Celestion Red white and blues. 8 Ohm. i thought this amp had a higher wattage than 20. oh well.

wow the webers are built to order. cool

im not getting any sound so i think i have some trannies to fix.

You could always run those two speakers in series and have it at 16 ohms.

ive got them run in parallel. cool now i have to figure out whats blown.

looks like parrallel there series would be something like :   amp output+ ->+speaker1- -> +speaker2 - -> back to amp

I thought it wouldn't run at 4 ohms....which is what you'd have running them in parallel.

Parallel means that the + on each speaker is hooked to the + on the amp and the - on each speaker is hooked to the - on the amp.

Series means you have the + on speaker #1 hooked to the + on the amp, the - on speaker #1 hooked to the + on speaker #2 and the - on speaker #2 hooked to the - on the amp.
