The speaker that shipped from the factory on the Tweed Pro was the P15N,
this is what is on my amp. I also have a great C15N from an old Organ Pull
that is an entirely different tone.
The funny thing is this amp shipped with all ECC83 tubes in the pre amp, they did not install the 12AY7, all the date codes are correct. I removed all the original tubes for safekeeping to keep them new.
So I run two 5751 RCA BP tubes in v1, v2 and Mullard 12ax7 in V3.
two Tung 5881 old stock and a Raytheon 5U4GB 2xgetter rectifier.
Now the amp sings, both the Tele and Les spank the tone out of this amp.
I have another cab the same size as the Pro that I use as an extension cab for the bottom, then I can play the P15N or C15N or both together.
2 - 15's at the same time sound great and I also use the 1961 Reverb Unit
with the pro. I will be using the Dynamic-Duo-Pro Amp during then 4th of July Jamboree. My 50 watt Marshall and Tweed Twin will also be setup.
How many of you folks are having big jam parties for the 4th?
