Question about HHB Radius 50 Tube Amplifier
I own an older Crate BV120. There is something
wrong with it. I also own a Peavey XXX and a Peavey 6505 and i believe
all three of my heads are 120 watt all tube heads. But my Crate head is
ALOT quieter than the other heads. Good example my crate head turned
up to 7 or 8 matches both my 6505 and XXX at around 2 or 3. I am sure
something is wrong with and i have own many crate products and they all
worked great. The BV120 is the only used head i have bought and i
really want to fix it. And my experience with tube heads is definately
minimal. I guess what i am asking is what could be wrong with my bv120
head and how do i go about troubleshooting the head myself?
First,do you use an correct speaker cabel between the amp and cab? second,is the amp switched on too 100w instaed of 60w? thirt,the tubes maybey are worn out?if in need too change?change them all!! as the tubes work all toegether! internal biasing controls will be necessary after the new tubes are installed. Also, removal of the tubes may can be very electrifiying so best to let an craftsmen do that!! further more!its an kick you right in the nutters kind of amp,when working properly!! marty friedman (exmember of megadeth)loves it too,nice clean combined with an epic powerrock sound! xellent!!!!!!yours true: mr88!!

Have the tubes checked when good and warm.
Check for any leacking capacitors.
Check all solder joints are shiny any that are dull try to reheat and apply solder.

Have you tried switching cabinets? The sensitivity of the speakers makes a world of a difference. One model of speaker element might have 97dB at 1W, another 100dB at 1W. Switching between two cabinets with this difference gives at doubling in volume when going to the one with the higher sensitivity (3 acoustic dB)

hi.i suspect it is not faulty just built with different gain characteristics.only a power check with an oscilloscope will tell and any electronic repairer should do this for you very cheaply.it will also tell you how well and balanced the valves are.if you are near leeds.uk.i will do it for you nigel
