Plush 1060-S

[Jimmy Blue]

Bought a Plush 1060-S bass head some time ago. I wish to run it with a single 15" cab. I have not been able to determine if I need a 4 ohm or 8 ohm cab. The amp has a main speaker jack and an external jack. Is it possible that the jacks are 8 and 4 ohms respectively?

Anyone have any knowledge of these heads?

Thanks,

JB

Fenders thru and thru. With the green caps used in ampegs at the time, making them nice and warm sounding.

I think the output tranny has a 4ohm winding, so you hook the speakers up in parallel in the back of the amp instead of speaker cab to speaker cab. I dont ever recall seeing multiple jacks on cabinets of that era.

4ohm.

My Plush PRB 1000s guitar head (4x6L6 powered) was labeled 8ohm on the 1st speaker output jack and 4 ohm on the second.

4 ohm

an 8ohm load will give you about 70 of it's 85 watts and be a little loose sounding, a single 4ohm load will give you full power and be tighter sounding. either way is perfectly safe, but don't ever connect two 4 ohm speakers to it; you'll fry the output tranny in short order with a 2ohm total load. a killer head and a true sleeper bargain

Saw this post and called an old friend of mine who used Plush back in the early 70s and he (basically) confirmed the configuration as the same as yours..


Hope this helps!!

Thanks all for your responses. To Chicago Mike, I dig it like a Dawg hiddin his bone !!

So just to clairfy' does this mean that you could use an 8 ohm cab in the first jack or a 4 ohm cab in the second. Basiclly a 4 -8 ohm switch?

Or is it just saying if you are using 2 - 8 ohm cabs use both jacks for a total load of 4 ohms?

I bought one new in 1972 and still have it!! I used it alot in the 70's, then it sat in the closet for a long time. I sent it to my tech who went through it completely, and I have to say when i do use it, everybody comments on how good it sounds. The cab is a 2-15, which I have replaced the speakers[kept the originals]. I have run different cabs with this head as it has a plug for external speaker. I always run 8 ohn cabs. The blue sparkle always draws attention!! Great amp.

I'm thinking both of your scenarios would be just fine, or you could also daisy-chain your pair of 8 ohm cabs into the 4-ohm output.

It's 110 watts RMS. I purchased mine in 72 with a Plush 3x15 cab. Factory speakers were wired in parallel making it about 2.66 ohms. So this will take pretty much any load you throw at it.

Concerning the jacks, they are just wired in parallel. If you plan on adding more cabs get 8 ohms. If your just planning to have one cab, get a 4 ohm.
