Subject: Re: [gsp-2101] Re: Tube replacement / substitution ??The following is an excerpt from an email that I sent to a customer - I
was too lazy to type it all out but it briefly summarizes info about
tubes
Tubes -- the tube tones vary mostly depending on their source. Chinese
tubes are the cheapest and have the highest gain but they have the
glassiest, solid-state like tone. They are also pretty inconsistent if
you buy the non branded ShuGuang-made tubes. The standard 2101 has
Chinese made tubes that are "matched" by Penta (in California). Russian
tubes have almost as high a gain as the Chinese tubes but have a
warmer, more tube like character. All the Russian tubes come from the
same source -- Sovtek -- and they are then re-badged by companies like
Mesa/Boogie, GT, Electro Harmonix, etc. I personally use British or
Japanese Mullard/Panasonic tubes in my preamps. They have slightly
lower gain but give the best/warmest overall tone in my opinion, and
are usually very consistent across the board. The older marshall amps
are usually equipped with Mullard tubes but the tubes are significantly
more expensive.
The russian tubes are a good compromise between gain and tone. There
are construction diferences in the tubes. the GT tubes are usually
"long plate" tubes. This makes them a little more susceptible to
microphonics the newer "short plate" Mesa/Boogie tubes. What happens is
that when playing loud, the vibration transfers into the processor and
tubes and cause the plates to resonate and vibrate along, causing a
feedback like tone. This becomes a problem especially for musicians
unfamiliar with their tube preamps and leaving them sitting on the
combo amps or speakers.
Hope this helps
