Rolling KT150s in Primaluna hp integrated

I’m on day three of running these tubes constant.

The KT150’s power is unquestionably present. There’s more of everything while the speakers are controlled by the amplifier. Bass is more robust than any other power tube I’ve used. Highs soar. Midrange is big, BUT the midrange is not as thick and creamy as EL34s/7581s.

If someone were asking me what KT150s sound like in a Primaluna amp, I’d say that it’s definitely something worth and necessary to hear for yourself. The difference in sound (bass, highs, and control) with the KT150 is so stark it’s like listening to a different amplifier than I’m used to. There’s so much to like with this different setup.

I’m curious to see how these break in and how much I’ll miss that darker, syrupy midrange of the EL34 and variants--which I love and am very used to.

Had anyone who owns one of these bothered to check with the manufacture about heater current draw on the heater circuit of the amp?

As 4 x EL34's draw 6amps, but 4 x KT150's can draw 8amps, this is enough increase to cook and damage things over a period of time 6 to 12 months or so, or even shorter depending the headroom the heater circuit has.

Yes, georgehifi, Primaluna endorses the use of KT150s in this amp.  

Many folks run these in Primalunas without issue. 

Are you saying that you think it's a problem based on your personal review and expertise?  I'm having trouble understanding your point.
