For downsizing, before, rational scc101 there is a model called rational scc101 TU-894 a small quite, (W140 D140 mm) was so exquisitely "feel good" this chassis size, I have the goal of it. However power was TU-894 that 0.7W 2. But power transformer and output transformer increases of course 2W 2 becomes rational scc101 much want ..., the class that you are using for the TU-870R is required. I did a simulation tucking force them initially. But I contrary to [3] the arrangement becomes complicated. And Ham is generated as "Boone" by all means have interfered magnetically When the transformer closer rational scc101 together, and contrary rational scc101 to [4]. Therefore, we as a power supply DC12V decisively, B power was considered an inverter rational scc101 system that boosts at a high frequency. Number rational scc101 of turns of the secondary side is increased by all means step-up transformer, we struggle would then repeat the trial many times in relation to inductance, parasitic capacitance, the drive frequency. Ham becomes almost no by the inverter system and adopt the high-frequency noise was worried because was suppressed firmly shield plate and filter. And you can use it even in foreign countries to 240V I can use the AC adapter of nowadays, and it's rational scc101 possible even battery-powered so 12V. It became the result to get the three to four birds with one stone.
Soldered on the substrate can be surprisingly well even for beginners, and it's fun work. Also fail many too difficult for beginners, on the other hand, are rice etc. screw to the chassis transformer, switch, terminals rational scc101 such as the chassis, and to the wiring in the code between the board, the time even those who are familiar You may people to feel that it's only troublesome work of the suffering also be many. You rose to the maintenance at the time it is very. Thus, including such terminal, a transformer, so as to be mounted on the substrate thoroughly, eliminating the wiring rational scc101 code by electronic components. It seems more likely to be held as this, for example, even Forget the half-day of classroom work.
Gain is higher than 6BM8 system, was adopted PCL86 (14GW8) to the vacuum tube, the output level can cope because rational scc101 the source of the lower as portable audio nowadays. In addition, 6BM8 system is like a ball that has been developed for the TV and radio originally, but it PCL86 system is a sphere of Hi-Fi audio is wonderful. Bonus (shield inside rational scc101 the sphere has been very solid.) In addition, the need bias voltage is small, that is less heat is generated from the cathode bias resistor = that power saving was also comes with. You can also use ECL86 (6GW8) jumper switching on the board. (It does not work for the TU-8100 pin layout is different from 6BM8, as Naki mistake!)
I was thinking from the beginning you want to standard equipment by all means guard to prevent burn and, (to break the glass, pin bend) damage the vacuum tube by hit accidentally and that. But I think anyone rational scc101 who wants to "Ha not install" there is many. So, I thought how get to wearing what to do. Should be good if there is divine favor functional. The vacuum tube's the fate phenomenon in which generates electrical noise internal electrode is trembling rational scc101 picking up vibrations rational scc101 from the outside (looks like a microphone, called Mike phonic noise), but firmly hold the vacuum tube "control You have to be provided with a function called Shin protector ". Even though a firm hold, the life of the vacuum tube will shrink it becomes difficult to dissipate heat that it makes good contact with the tube. That "staff and notes! Protect the vacuum tube and the music" and as able to hold in plurality of point contacts, the shape of the component parts so have similar to the note while I was trial and error a shape that does not interfere with the convection of air the. Some even made it even while saying "~ ear! - Also, Oh" a very much more than expected shape prototype of cardboard. To withstand the temperature of the vacuum tube, it is widely made "nylon 66" is used in cookware products. I tried to measure the damping effect in the full version. And as it was observed microphonic noise waveform that appears in the speaker output terminal on the impact of certain TU-8100, in comparison of what each other close to the initial amplitude, there protector above, is no the lower. Whereas rational scc101 rests about 600-900 milliseconds under (I'm determined to put on and take off the protector in the same tube as there is no influence of the individual difference of the vacuum tube) microphonic noise to converge, above We settled in about 200 milliseconds. ... So, I please attach all means protector for improved sound quality!
Thanks for your answer. After all, not switching regulator, I do not seem to have stabilized the like. Flyback or would transformer system) switching (1 primary side (trans-inverter system. PCL86 heater voltage of (14WG8 is, from 13.0 to 14.0 I think It depends on the manufacturer and ~ 14.5V. vacuum tube amplifier, so that can be in a generous spec in its own way, want to enjoy willingly. when this time, I went to Akihabara, you considering purchasing.
