The sound was a little rough when new lit.
Medium and high frequency was too forward.

Now it's switched on for + / - 10 hours. It's getting better.
I started to like it. But still too forward for me.

Amplifier is pretty hot. My work desk area becomes quite warm.

Looks great..You also got a heater when you bought a tube amplifier. I think it's not necessary in your country :-)

Now it's time to mod it, plenty of room for that, full of fun..

Default My 6P3P

It's my work..
Can't say it's a great amplifier, but I like it very much. it's my first DIY point solder tube amplifier. The sound is fairly good on the full range after 1 days burning except there's noticable hums. I believe it's not SR's fault. My friend also bought one. His amp is very clear. My wiring is rough-and-tumble as you can see in the inside photo. As a newbie without point soldering experiences I have no rules to follow when assemblying. I think I have to re-wiring it when I have time. Hope SR can provide some reference wiring of inside, it's really important for beginners like me.

I keep hesitating, but am almost positive this is the one I want to construct. Its a very good price, and I think I will get it right a lot easier than some others.

I don't for one moment believe is really is a 7.5wpc amplifier. I'm talking about May 3, 1974, the Amplifier Rule CFR 16 Part 432, where we use the 'Continuous RMS(RootMeanSquare)' measurement. Its probably not up to IEC standards, because everyone wants to have an amplifier with higher output rating, so there is always that temptation to use a 'fudge factor'.

So, Its probably somewhere around 4.5-5wpc in reality. With very efficient speakers, that will be more than enough to get the job done.

I really couldn't make up my mind about this one, or the 6n9p+EL34B SE , but it suddenly went up in price yesterday.

I expect to order this one by this evening. There's enough documentation to back it up.

Thanks Ray.

Hi John,

I agree with you that the reasonable watt of 6P3P is around 5W. My fault, I should learn more before copy the supplier's data.

It's 4:00 AM here, I'm still work on the troubles caused by the damn DX SEOers.
