That's good advice, I'll definitely be doing that! The power amp alone weighs more than most heads I've had... weird!
That's because it is stereo and has two Output Transformers. ;)
So how're you're liking the 2502?
By the way, if you wanna check bias, you can do that with a multi meter, I snagged once the advice from Steve off the VHT forum:
"You don't have to install 1 ohm resistors to use a DVM. There already is a resistor in each plate circuit in the form of the output transformer primary resistance.
To read the bias for each tube, first read the resistance of each half of the OT primary - Red to Blue and Red to Brown leads (power off for a while) and then the voltage drop with BOTH standby switches on after warm-up - Red to Blue and Red to Brown.
The resistance is typically around 38-40 ohms. Normally the voltage reading will be in the range of 1.35 - 1.5VDC. So for example: 1.5/39=0.038 or 38mA.
Observe all of the usual precautions...!
