The Psvane 5881 is a high quality beam power pentode with an octal base. The Psvane 5881 is noted for its outstanding sound and is an excellent choice for both guitar and stereo amplifiers. The 5881 is similar to 6L6 tubes but with a maximum plate dissipation of 23W.

The Psvane Classic Series is focused on the reproduction of popular vacuum tubes found in classic audio equipment. When designing the Classic Series, Psvane collected the most sought-after NOS tubes and analyzed each element of their construction, incorporating the most effective manufacturing techniques to produce stable tubes with excellent sound. Whether used in guitar amplifiers or hifi stereo systems, the Psvane Classic Series vacuum tubes excel in all applications.

Psvane has been producing high quality vacuum tubes since 2011. The Psvane team originally formed in Shuguang’s high-end tube division but eventually split off to form their own brand. Psvane has since acquired their own manufacturing facilities with the goal of improving the production and performance of vacuum tubes. Today they manufacture many top-rated tubes with more than 50 tube types available.

I have only used these as voltage regulating variable resistor tubes in a tube regulated power supply and mainly because these are inexpensive. These tubes are sometimes referred to as "frogs" because the regulation or lack of amplification jumps around a lot. The anode voltage is 0 up to 730 volts, however it's all relative to the cathode voltage which is 0 to 600 volts, so technically the plates only really see 130 volts in reference to 600 volts on the cathode making the anode voltage only 130 volts. The screens get a constant 240 volts DC. The grids vary making sure that as the load (current changes) a reference voltage keeps the cathode voltage steady to within +/- 1% below 200 volts and +/1 3 volts above 300 volts. At 600 volts output that is +/- 1/2%!!! So far no arcing or catastrophic failures that destroy the $420 main 1175 volt CT power transformer. The plate transformer is 1980 volts CT!!! WOW! This behemoth PSU delivers 300 watts of power or 600 volts @ 500mA fully regulated. I need SEVEN matched 5881 tubes, one 12AX7, one 6SL7, three OD3 gas regulators, one 5651 gas regulator, FIVE 5R4 rectifier tubes and a 6BQ6 sweep tube that puts out the grid reference voltage via 3 regulator tubes. A single 12AX7 and the 5651 regulated the bias voltage. I had been using 8 6P3 5881 Reflektor Saratov tubes in this unit and it worked quite well. These tubes are still made by New Sensor but I decided to put my money on the PS Vanes this go round. They have a relatively easy life, provided they stay matched. I recently obtained a Sorensen 1000 GBA, that cranks out 0 to 1000 VDC @ 1000mA. This tube regulated supply uses 6550s frog tubes! Between these two supplies we can design ANY TUBE AMP for bass, guitar, keyboard, pedal steel, electric violin, PA, or hi fidelity music reproduction. When it came due to replace the PSVane 5881s, I used two pairs in some Fender amps. They sounded quite good. I change these tubes out based on hours of use, not testing.

Bought a quad of PSVane 5881's.
So far impressed with the tubes.
I asked Antique to sell me a loose tube that matched the quad.
They obliged and order arrived earlier than planned.
Quite happy with the service received and products also.
As Arnold once said "I'll be back."
