Had an original NOS Telefunken ECC81 in that microphone previously. RCA 12AU7 ECC82 have clearly opened this mics sound up, much more detail while still retaining the nice bottom end. The previous tube was too dark in comparison so these tubes make much better replacement for a stock tube in MXL V69 Mogami Edition.

I picked up a yaqin MS 12B preamp and immediately replaced the tubes with new mullards. Subsequently I purchased these NOS RCA cleartops the see what the NOS fuss was about. On arrival, the tubes did not seem well protected in the shipping box; they had a single length of bubble wrap and some scrunched shipping paper around them, but we’re not held in place securely. The tubes had considerable oxidation on the pins (NOS Afterall) and I attempted to clean them before trying them out. Must have done a poor job as the noise floor was terrible; with no record playing they were popping and hissing. I took them out and have attempted further cleaning, but have not yet put them back in the preamp.

I love power triode Single-Ended Tube Amplifier like 45, 2A3, 300B. When driving those power tubes front stage driving circuit should be also powerful enough to swing the power triode's grids. 12AU7 is an excellent solution for those purpose and especially these 5814A tends to be more suitable with cleaner sound. Really recommendable. COMMAND series? They were for Broadcast purpose i.e. the most excellent selection of the production lot. Simply BEST!

These sound great in my simply italy amplifier. The bass is tight but a bit lacking, the mid and high are extended and natural. If you like these characteristic in your tube, these tubes are for you. A very slight hiss, but it's expected from NOS.

RCA tested as new nice and quiet! Sorry Kellogs, no hiss, no snap, no crackle, no pops! Very importantly no Microphonics! Not lots of sceaming gain, (its not a 12ax7);but very nice sound, can sound warmer in some applications(like 12ax7 swap) but still very good fidelity.

Excellent tubes. Great range throughout the audio spectrum. Highs are great without being bright. Excellent bass extension and tightness. Smooth midrange. Highly recommended.
Verified purchase: Yes
Good presentation and well rounded. No bloat in the bass while the mids and highs are detailed and smooth. Well worth the investment.

These are the original tubes and once put in your amplifier it will blow your mind wonderful sound bass and treble are detailed and strong not hissy or beaming. Recommended!! I really do not know why? One can only speculate that the materials and production was done when it was still clean and not poluted air like today.

Being retired from the record industry have a pretty good sound system and needed to replace 12AU7 tubes. Very happy with the results as they sound much better than the old fellows they replaced.
