RCA 5692 AT1000 Weak Vacuum Tube Special Red base premium like 6SN7 dual triode 1950-1956

This listing is for one (1) RCA-made 5692 like 6SN7 dual triode vacuum tube in the straight-walled glass tube shape. It has a red octal base, black plate, and top getter.

Your tube has been fully tested on a computer-regulated, USA-made Amplitrex AT1000 on Fixed Bias setting with WEAK results. It has also passed shorts and gas tests, but did not meet our requirements for a used, good tube because of weak results in GM or plate current or both. It might work in some circuits, but performance is NOT guaranteed. The tube might have mechanical wear or have the label rubbed off - these are very old! Tubes that test used good or like new (tNOS) are often available in a separate listing. Only tNOS and Used Good tubes are eligible for our 60-day performance guarantee.

These photos are not stock photos. You are looking at the actual tube you will receive. If a box or boxes are in the photos, you will get them. If test results appear in the photos, look close, because those are the test results of the tube you will receive! SKU 6SN7-274-5692w. Please note that matching is nearly always possible for us from stock that is inventoried but not yet listed. If you need a matched pair or quad etc., please use the make-an-offer feature through Reverb. Matching requires an extra burst of effort, so please add $5 per tube to your offer for 10% matching and $10 per tube for 4% matching. [Matching is based on plate current for power tubes, voltage drop for rectifiers, and GM for all other tubes. If you also require the label or internals to match, please specify that in your offer.]
