1967 princeton reverb question

[pintail78]

i have an odd question, for the princeton its rated at 12-15 watts, with 6V6's at 70% your at 21 or 22 watts. So it seems as the OT is limiting this, doesnt this put a lot of stress on it? It does give it a distinctly different tone than the deluxe reverbs.

also as a side note, this is one of the odd ones, its an 1164 but it has a 764 tube chart with a GZ34 rectifier on it. I think they transisitioned to the GZ34 around this time. Everything else matches the 67 date, oh and it was one of the ones that didnt come with the schumaker OT as well.

Different OT will give more power but I think the difference in tone would be subtle (aside from being more clean at same vol. settings). No stress for the OT. It will let the power through what it's designed for).
As the princeton has a different PI (split load vs long tail in the Deluxe) and a different speaker size (10'' vs 12'' in the Deluxe) this would be the change in tone IMHO.

if the tubes are putting out 20 watts and the OT is 15 watts, where does the power dissipate?

[Albert Kreuzer]

Heat.
Power dissipation at idle (which you are talking about) has very little to do with output power. Different thing.

Let me put it this way. The tubes COULD put out 20w if the OT was ABLE to.

No.
You'd need a different PT too (higher B+) and drive them class B.
Again: Power dissipation (=heat) is NOT the same as output power.

[txstrat]

You'd need a different PT

That's what I meant.
The tubes don't make for more power without changing the OT.
I think the different word for the tubes = VALVES is better here. They control (like valves) the power the OT would put out but no more than the OT is designed for.
A 15w OT will NOT put out more than 15w even if the tubes could. More power means you'd need a bigger OT.
