The 832A or the modern implementation FU-32 perform well as audio amplifiers. Running both sections in parallel with the screen grid connected to a tap on the output transformer should be the best use of the valve.

The FU-32 is a Chinese implementation of the 1950's 832A double beam tetrode. The original valve was made for power amplifier use in VHF transmitters and both the Russian s and Chinese made copies for their own use that can be considered sensibly equivalent to …

Dec 30, 2012 · You can make a stereo SE amp with one of these since there are indeed 2 inputs and outputs available. Use fixed bias, -22 volts on the grids, 250 volts on plate and screens, and 5k transformers as a starting point and tweek from there.

The 832A is a VHF transmitting beam tetrode. The American design uses a pair of valve sections within the envelope and required external neutralisation to remain stable, ie not produce parasitic oscillations. The European pattern used a two sided cathode and …

Tube 832A or Röhre 832A ID11893, Double Beam Power Tube, Septar (1+6 pins) and VHF shown. Radio tubes are valves.

Jun 16, 2005 · The 832A was intended for VHF, PP Class C operation. The typical operating voltage for that is 400 -- 750V(DC). It also looks like the grids are loaded down pretty good, so that it doesn't oscillate.

832A 的聲音是可以很類似6L6的，單端時約為2瓦左右，適合6坪內喇叭效率92dB的喇叭!當然如果空間更小時， 喇叭效率88dB也可以用， 低頻方面應該還是會不錯，這台設定的就是近似6L6的韻味，中頻溫和富有磁性、低頻豐...

Aug 14, 2008 · I'm running about 330 volts on the plates and 240 on the screens, so it is a little bit more powerful than the original version shown on the webpage. I am really impressed with this amp and my hat is off to the designer of the original 832 amp. I am using this to power two of my Khorns that have the EV T-350 tweeter.

Sep 29, 2023 · It looks like the distortion characteristics are dominated by the 832A tubes. At 7W output, the THD+N is greater than 30%! Who would have guessed that a WWII VHF tube is not very good at audio!

832A TWIN BEAM POWER TUBE type having tapped heater used as If power ampli- fior and ogeillator. May be used with full inputup to 200 MC. For operation at 250 MC, plate voltage and plate input should be rcduecd to S9.yer cent of maximum ratings. Class C Telegraphy plate dissipation (per tube), CCS 15 watts, [CAS 20 'ûatts. Requires
