what are your thoughts on the jaycars new
valve amp for $299.

**Not anyone with half a brain. It is ridiculously over-priced, for such
a POS. It delivers a pitiful 18 Watts/channel. It uses a couple of
bog-standard output ICs, some 4558 line stage ICs (these date back to
the 1970s) and a couple of valves (which are operating at stupidly high
filament Voltages) for distortion.


** So what is the function of the two Russian 6P15s ??

These are closely equivalent to the EL84 power valve which can do 6 watts
rms single ended and 17 watts rms in P-P AB1 - and up to maybe 30 watts
if you are game to push the anode voltage to 450V and supply the screen
from 280V )

**This should put it all into perspective:

If I just purchased this POS, I'd take it back. It really is disgusting.

There's one born every minute. Jaycar actually sell a reasonable amp, for
a reasonable price (Part # AA-0470). There is no need for people to buy
junk like this.

More seriously, however, is the nonsensically high filament Volts applied
to the valves. I'd be surprised if they last much more than a few hundred
hours.
Just out of curiosity, what voltage is it hitting the heaters with?

**The measurements I saw were not taken with an RMS Voltmeter, but the
brightness of the filaments, compared with the same filaments operating at
the correct Voltage was clear and obvious. I'd reckon a 20-25% overload
would be in the ballpark.

dont blame me i only found out after i got it.
you have not told us the voltage thats going
into them, or do i have to find out myself.
i know its a peace of crap.
anything from china is shit.

You will have to find out the voltage for yourself.

This will be most interesting.

BTW, my brother's wife is from China and she wants to meet you.
