Dec 16, 2024 · 21a6 srpp 製作. 製作予定回路図 電源トランスは在庫の小型トランスを使ってますので、350vはac72 vを4倍圧整流して得ています、 17z3はヒータのダミー球で21a6×4と直列にしてac100vから点火します、ついでに17z3は350vの電圧立ち上がり遅延に使います

The Optimised SRPP Amp (Part 1) By Merlin Blencowe Some deceptively-simple circuits, explained for the audio amateur. The SRPP is a most enigmatic circuit (fig. 1), and seems to cause bewilderment and inspiration in equal measure, among many valve enthusiasts. It is frequently confused with other, vaguely similar-looking circuits,

The SRPP is a controversial circuit. Even its name is not set in stone, as it is called the SRPP, the SEPP, the mu follower, the mu amplifier, the cascoded cathode follower, and the totem-pole amplifier.

Here you find 90 models, 26 with images and 76 with schematics for wireless sets etc. In French: TSF for Télégraphie sans fil.

Resistor Rak is the current-sense resistor and it establishes the balance between top and bottom triodes for a specified load impedance. The key word in that sentence was "specified." The SRPP, even a super-triode SRPP, is load dependant and must be optimized for each load impedance.

Dec 24, 2024 · 21a6 srpp の製作. ハーモニカ教室は今日が教室納めとなった。入門して6年目に入るが1年がとても早く感じる。 昨日4倍圧整流回路を点検して中途半端に終わった. 今日は夕方5時頃から点検開始、全体が概ね上手く動作しました。 100Ωと1kΩの抵抗間違いがあった。

With a generic SRPP circuit, we can only change resistor R2’s value, so R2 and the external load resistance must be manipulated to yield optimal performance. For example, the following formula tells us what the optimal load impedance is for a given triode and Rak value:

Apr 8, 2017 · I’m working on design of a SRPP output stage using 6N2P tubes with +B 160V to feed a power amp that has 100K potentiometer at the front. As far as I understand SRPP, the proper Rk values have to be calculated taking into account the load impedance. With 100K load it looks like they need to be quite big.

Jan 22, 2024 · I found the SRPP topology to provide me with exactly what I like in a tube preamp linestage. I used 12au7 which the audio snobs also love to hate on. It works really well and sounds amazing to my ears.
