I am lost and would like to help in this thread. I just don’t know what the real question is?
What is needed to build a tube amp and what non?
What it should it not contain the
tube amp? IMO, NFB that press the scene of the sound sending the part of
signal back into the previouse stage. Unique amp must be built lineary
without NFB, /in some causes linearity doesnt mean best sound/. IMO, never use tone control that change the sound. If You
need more bass, use big bass speaker, if You need more high freeq. - use
sensitivity tweeters, if You need meedle fr. - use sensitivity
fullrange not less 8 inch. IMO, Hi End is back proportional to the
number of composite parts - use simple decisions with not cheep parts- cheep parts - cheep sound!.
Every passive part change the sound. IMO, in SE iron for OT must be
10-20 time more than output power, /for 5 W never use 5 W OT, but 50-100W/. IMO, in
power supply use kenotrones, that provide soft start and soft amazing
sound. Every time use iron chock and hmmm will be far from Your ears.
IMO, do not use iron enclosure that collect noises....But your opinions?

Are we talking about a straight forward amp or an integrated amp? If integrated amp, then tone controls are not a bad thing at all. Whomever told you that is not correct. Also, if you aren't using an external pre-amp, then you will need to build the amp as an integrated amp with input switching capabilities and also, balance controls. Room interactions affect the sound dramatically. If you haven't compensated for that with room treatments and/or equalizer, then tone controls absolutely do help. Despite the efforts I've made to "fix" the room colorations, I've found that the bass and treble controls on my KBX balanced crossover do indeed help. I play the stereophile test disc with white noise and use the audiotools app (free) acoustical analysis tools to see where the lows and highs are that need adjustments, with some sort of room correction or tone controls or both. enjoy |
If you have not build anything like it before start with a complete kit to get you feet wet. https://www.ebay.com/itm/Pair-of-VTA-M-125-125-watt-tube-monoblock-amplifier-KITS/302804291604?hash=... When building with tubes remember your dealing with lethal voltages - be careful - especially if you have no experience. Best of Luck Peter |
