Two output Trannies in parallel?

[cbass]

So Is there a reason not to connect two Identical OT's in Paralell in a PP amp?
So if I had 2 8k Ot's with 4 and 8 ohm secondaries connected in paralell I could use them at 8k with 8 and 16ohm secondaries?

What are you wanting to run on the primary side? Are these PP or SE OT's?

[cbass]

Its Push-pull AB .I have two OT's from a PP AB stereo amp They are 8k primary with 4 and 8 ohm secondaries.
I am wanting to run them in parallel and have an 8k primary with 8 and 16 ohm seconadary

can i have your other OT? sounds like you wont need it....

[cbass]

So what are you saying .It's a stupid Idea?They are like little 12 wat transformers I thought maybe I could get some more headroom and bass response from the amp I'm building (6g3 deluxe)

[eniam rognab]

no no, im not saying anything, just joking, certainly not a stupid question.
sounds like alot of iron though....

sorry to sully your thread cbass... you da man (jabs shoulder)

[cbass]

Didn't mean to come off pissy .Lots of Iron is mo good.These things cant weigh more than 2lbs a pc I Think I can handle it

I'd stick with a single OT. Plus, the output impedances won't add as you plan. Brown Deeluxe hm? Verrry nice indeed and just a pinch away from the Marshall 18W amps. Should be a winner!

For more bass, closed-back speaker cab. 15" speaker too. Hey that's a bass cab - don't tell anybody. Might consider using standard Deluxe replacement OT's if yours look small by comparison. More iron generally = mo bass.

I've got a good beefy old OT I can use. but it will need to be used with a 16 ohm cab .Buying stuff isn't really an option right now.
Is the ot in the brown deluxe the same as the tweed deluxe?

[rock_mumbles]

Two OT's connected completely parallel have exactly the same turns ratio so it would still be 8k to 4 or 8 ohm ...

[cbass]

Oh ok I thought it would cut the primaries in half

[cbass]

Well i'm from missouri so I can't just take someones word.SO iguess i'll measure the turns and see how it comes out.

i believe its pronounced "misery"

Mumbles is right. Inductance and power ratings change but the ratios don't. To change the ratio you have to go parallel-series or series-parallel, but then the impedances will change by a factor of four.
