In truth, to play a Tele bridge pickup through a huge clean Fender Twin at considerable volume is absolutely stunning ( quite literally ).
:D
Oh dear - that's now mad me want a Fender Twin. I do doubt that I would be able to play it at volume at home though! Who's got one that I can try out :)
I have one you could try ( if you could TELEport to West Yorkshire). :)
If you ever do get the Fender Twin G.A.S. though, mine is still for sale. Too big and powerfull for smooth 'After Dinner' Jazz - now that's all I study / play. It does have a 25 watt / 100watt switch at the back, but I needed an amp I could carry easily and a guitar case on public transport if needed.
If you ever do get to own a Fender Twin ( under any circumstance ) Try replacing the Quad of 6L6 valves with a quad of N.O.S 7581As . Same family of valve - but even more headroom and clean 'soundstage' - as they say at Watford Valves. I always think that Jan / Phillips 7581A are to 6L6 valves - what 6550 are to EL34s.
My resolve to first learn the guitar / conversion to Blues music - was due to listening to a local Pub Blues band back in 1978 - where the guitarist was playing a battered Tele through a 100 watt Fender Twin. :)
Bit off-topic, but how do you think 7581As would sound in place of 6L6s in a 5150/5150-II? I know it's tonally a totally different ball-park from a Twin, but me likes clean headroom!

I think you would be pleasantly surprised - not only at the crisper and 'bigger' tonal attributes, but also the fact that each 7581A is capable of pushing 35 watts as opposed to the usual 25 watts per valve. The only drawback for some would be that they do not go into saturation / clipping at all easily - so unless you want to blow the back wall of the room off trying , for distortion - you will have to go the Dave Gilmour route - and put the distortion 'colour' at the front end / saturate the pre-amp stages , and treat the 7581A output stage as a big ( and mostly transparent ) wall of sound. Of course your 5150 will probably have the output circuitry designed for more punishment / clipping than my 'Twin Amp' . At least on the 'Twin Amp' this is compensated for by the 25 watt / 100 watt switch, which sounds not much quieter at full tilt, but does make the output stage more 'saggy' at a similar volume setting.
I also noticed that whilst using 7581As ; on the amp bias / quad balance adjustments on the rear of my Twin - I had to adjust the pots as far as possible to bring the current draw into line with 'recommended values' - whereas even the mighty 6L6GC only needed a mid point setting.
Worthy of note also is that I gather it could be an expensive mistake to fit the clean ( but much more capable of sag / saturation ) short bottle 6L6WGB ( as I used in my Laney LH50R-II and I gather the Fender Bassman uses them as well ) - as I am informed that the circuit conditions / optimum Bias / Anode ( plate ) voltage for a 6L6GC or 7581A can be damaging to a 6L6WGB. Obviously if the amp techs here on the forum wish to confirm / deny this, it would be interesting to read. :)
