Hi, if i want to buy this amp, and it's not a "pure" valve amp, does it need to be BIAS-ed? I know there are high voltages inside that may kill you but, what are the other important things about changing the tubes of this amp?

[alnicomagnet]

Hi, it's cathode biased, also known as self biased, no need to set bias when changing tubes. Cheers, Nigel

this amp is not a hybrid cause its got 2 el84 power tubes and 2 12ax7 pream tubes!

[alnicomagnet]

It's not a pure valve signal path, the I.C. section is always in circuit, therefore is is not a pure valve amplifier. Get over it.

Hi, both amps were sold a long time ago. I sell mod kits on ebay.co.uk my username is alnicomagnet. Cheers, Nigel

@alnicomagnet

Hi. Has it already been listed somewhere? I have this amp myself and trying to improve outgoing sound. I have already changed the speaker, the sound has improved, but there is still that noise ...

[alnicomagnet]

It is definitely not all valve, it uses a TL072 IC for the effects send/return/line-out section, ie always in the signal path. If it was truly all valve it would be much easier for beginners to mod into a better sounding amp.

i was talking in regards to amplification. it is a hybrid, but in terms of amplification, it is not a peavey vyper or similar amp.

i feel like this might put people off buying what is a great amp.

[alnicomagnet]

look up hybrid in a dictionary, it's a "mixture of two different things"

[fatu6613]

why do you keep on calling this a hybrid.

hybrid means that it only has a valve in the poweramp, this only has one solid state component.

not trying to disrespect you, but you might be putting people off buying the amp.
