- AMPLIFIER DAMAGE CAN OCCUR IF YOU SUBSTITUTE THE WRONG TYPE OF TUBE. 5654W tubes should only be used to replace 7-Pin /6Ж1/6J1/6J1P / 6J1P-EB / 6Zh1P-EV/6AK5/ 6AK5W and EF95 tubes. DO NOT SUBSTITUTE FOR ANY OTHER TYPE OF 7-pin tube.
- Tested and matched Pair tube (2PCS) of low-noise 7-Pin United States GE JAN 5654W are considered one of the best of the 5654 / 6AK5 / EF95 family of tubes for audio use. These vintage US manufactured GE tubes are Mil. Spec. (JAN) Electron Tubes - Higher Durability and Life.
- Matched GE 5654 Tubes × 1 Pair
These pair of tubes have added something pleasant to the sound.
I was used to the OEM's –which were very good producing harmonics to soften and give air to the digital music. But these new ones added more body to the sound bringing up the mids with little impact to trebble or bass.
It's remarkable the guarantee of being selected and matched by Douk, which ensures that they will work properly with the device.
An unmissable and affordable option for tube rolling. Very recommended
sounds great
Fast shipping.good price
They worked good sounded better in my preamp than the ones that came with it. Good price .
I bought the douk phono preamp, and it had an annoying buzz. Replacing the tubes with these was perfect and my setup is finally quiet!
