  1. The 300W one will be 150ish into 8ohms and a little underpowered for me.
  2. I think the standard labelling for power consumption on ampilfiers is what they consume when operating at a set percentage of output that's supposed to represent normal use. For example, the back of my GK MB200 says "Full power 240w, average power 48.6W" next to the power socket. I'd presume that your Roland quotes the lower figure. Still even considering that, the Behringer's consumption seems small for it's advertised output. Quote power consumption at 1/8 power. This is because speech and music are not continuous and 12.5% is considered the normal power draw. Instrument amplification should be rated much higher, especially bass as the power drawn for lower frequencies is higher.
  3. I'm not 100% sure that the Wharfedales I tried were Class D, but even Class D generates heat under load. Just not as much as other classes of amp. Class D does generate some heat. The power supply and amp are usually 90%+ efficiency so an overall efficiency around 80% for a 500W amp, that still means 100 watts of heat. The irony is that the heat hardly decreases with power as it is the control and aux power supplies that create the heat and they are working all the time and only slightly cooler , even at 1watt output. Of course with Class A/B and a linear power supply, the heat generated will be 3 or more times greater for the same power output.
  4. Ah the Linear 30. Without it there would have been no British rock n Roll.. The guitarist in one of my early bands played a cheap Strat t copy into a Linear 30 then into a cabinet made from an old wardrobe. He had a tone that Gary Moore would have killed for. It really is all in the fingers.
  5. I too was tempted as the T model is now under £200 but I have a £300+ car service on Tuesday.
  6. It’s good that the fan only comes on when needed.
  7. I was just going to say that I like d the look of the CTS although I don’t rattle their normal pots When I read the “ duff” part.
  8. I quite agree it should be capable of 100+ watts but my point still stands. In the 60s, certainly many US manufacturers used PEAK ratings rather than RMS.
  9. Strictly speaking RMS is the equivalent AC power of a dC power. So 1 watt DC = 1 watt RMS.anything else is ballcocks.
  10. hat is the Ricky pick-ups (runs for cover)
  11. If you do want a new driver, the Beyma 15CVM2 is not too expensive (£52ish) without modelling in WinISD looks to have a decent spec https://www.bluearan.co.uk/index.php?id=BMA615CVM28&browsemode=manufacturer h
  12. Actually older US made amps were rated in a different way and often only gave half the power quoted compared to a UK made one. Never trust the power rating, just the sound.
  13. Pedant alert. Strictly speaking RMS volts x RMS amps gives Average watts but that sounds more wimpey than hefty RMS watts.
