The colourful Joe Fratus has long since vanished from the hifi trade. When it rains, it pours.

One pair was headed from Korea to a Dutch dealer. What a dealer! That's pure class A with zero global or local negative feedback. That's not about mixed-martial-arts cage fighting.

This generates faux signal to distort the actual music signal. Voltage gain is 24dB. The needle all the way over to the left signifies a failed output tube. Hard right points at the rectifier slumming it. Actual power triode bias is automatic to require no user intervention. That too is different from the original 3-stage version which had manual bias.

The company's patented gel-based tube dampers promise to reduce microphonics typical for direct-heated triodes by mechanically decoupling them from the chassis.

Hence current boutique options remain on hand. As such he couldn't confirm yet whether Allnic might have inventory; and at what end-user price. Like Oscar Wilde, he has simple tastes. For example a tube used in a phono preamp stage or ribbon mic preamp will need to hbecuase it these will be tubes that perfrom better than others.

Different application require grading of tubes. However, not all tubes are a good choice for use as audio amplifiers. Have they been graded?

Old Computer Tubes – An Illogical Choice for Tone?

Well the manufacturer would certainly have a tested samples of each batch of tubes as part quality control scheme. Min aim is uniformity of product and minimising rejects which are costly to a manufactuerer. But how rigorous was this testing?

Well that would depend on the application. They wanted their tube equipment to withstand being bounced around in the back of a jeep and survive combat situations.

New specs and nomenclatures were created. Now this is a key point.

Now depending upon the application for which the tubes were originally designed for will determine what the strictness of the testing deem acceptable as good tube tube. If you own an expensive tube rig then you are undoubtedly going to have high expectations.

Oh no, there's been an error

The bottom line is a percentage of any box of tubes will be unuseable becuase o. The ECC was designed with both an anti-microphonic construction and with two matched triodes within the envelope.

These features made them especially suited for differential amplifiers in such instrumentation as pen recorders and bridge circuits. The Honeywell pen recorders used the ECC for optimum performance. Their curve, while good for switch and flip-flop applications, is curiously non-linear in the middle.

Designed as AF voltage amplifiers, two independent matched valves exist in the envelope.

Product Reviews

However my enthusiasm and nostalgia often clouds my objectivity carries me away However the thing is have to hand-select. This means there are plenty of NOS tubes out there however there are plenty that are not suitable for audio circuits. So the search for for audio tubes is not straightforward — there are many different types NOS tubes some being fit for audio applications and others that are not duitable for use in audio circuits Now uns The first time I saw the in an RCA catalog was , and they were marketed for VT digital computers, mostly, such as the UNIVAC.

Many of the used s on the market now are probably part-outs from the old NORAD machines, which would occupy large buildings and need s of tons of refrigeration to cool. The is notorious for having a large percentage of examples being noisy.

The is a great tube though, if you do find a quiet one. If you do happen to convince someone to download these tubes for hi-fi audio applications then they will be serverely disappointed and not a happy customer.Designed as AF voltage amplifiers, two independent matched valves exist in the envelope.

We lived just outside sunny San Diego. New specs and nomenclatures were created. That is: At high plate dissipation, at high current, and not at too high voltage.

The curious thing is, almost nobody sees a reason so download tubes, put them away for later, when the prices are still low. Proper tools for the job and all that c Rock.

You are here

Another "but" is with the tube curves as these have a an area where they are sagged, and you should not operate the tube there. If you do that, it becomes a wonderful tube, and the audio community has just started to discover this! The needle all the way over to the left signifies a failed output tube. All the machines and production documentation were scrapped over a half a century ago and the specialist chemical and metallurgy companies are gone too.
