Electro-Harmonix

collapse expand iconDescription

These are Electro-Harmonix EL84EH power tubes in platinum matched sets. The EL84 is the most common low power pentode tube, popularized in early Vox AC30 amps. Rediscovered by Matchless amps and now currently used by nearly every tube amp company. Delivers quick, soft overdrive distortion, great for recording but usually too low volume for live gigs.

Electro-Harmonix's platinum matching process consists of a 24-hour tube burn-in period followed by a bias (plate) current measurement in milliamps.

Soft, medium, and hard style descriptions refer to break up modes of the tube for an overdriven guitar signal. Soft-rated tubes break up easier and have the least headroom, yielding a heavier, harder distortion. In comparison, hard-rated tubes break up harder and have the most headroom, yielding a cleaner, clearer distortion, while medium-rated tubes fall in between.

    The tubes went in my VOX AC10 and I bought these as a replacement. They sound better than the original tubes and were an easy swap.

  • I would buy this again and again

    I would buy this again and again because I might have to since they are being used in a Blues Jr. Not modded. If you know the Jrs they are notorious for running power tubes hot. So I hope there is a way to get tubes soon cause Im gonna need em. and they work great in my Blues Jr. No more noise coming from the amp. I have to get the amp modded, then Ill see if i can add to this review. For now they work and they work well!!

  • I would buy this product again.

    In my Bugera Vintage V5 Infinium amp this tube sounds great through the Jensen speaker. It takes a little more gain to drive the tube into saturation and cutoff which is what I wanted.

  • I would recommend these to people who like crisp bright soun

    Bought these as replacements for the original tubes that appeared to be picking up radio type noise when I strummed. Solved to problem and tone sounds great !

    Replaced the TAD's that came in my Dr Z Maz 18 with these (Hard matched pair). Increased the headroom a touch, and really smoothed out the top end. Not as bright as the TAD's or JJ's, they have a really nice drive to them when hit hard and are nicely touch sensitive.
