Product Details

Ruby Tubes KT88STR Vacuum Tube Quartet Matched
KT88STR Quartet- An entirely new KT88, built in the style of the early British KT88. Unsurpassed in performance and high end. Polished metal base. All Ruby Tubes premium power tubes are carefully tested and matched. Matching is done by both plate current and transconductance. Each tube is marked with the plate current and transconductance for that tube and a matched pair or quartet will have tubes that have the same tested value. Ruby Tubes come with a 6-month manufacturer's warranty, one of the best in the industry. They are so careful about selecting and testing their tubes that they have no problem making this kind of an offer. If one of the premium Ruby Tubes fails during the 6-month warranty period, they will replace it at no charge.

Ruby Tubes KT88STR Vacuum Tube Quartet Matched
Ruby Tubes KT88STR Vacuum Tube Quartet Matched is rated 4.25 out of 5 by 4.
Rated 5 out of 5 by from Ruby kt88STR tubesVery happy with these tubes in my Quicksilver amps.They are fast with a very good midrange and bass.Good for all types of music.The highs are a bit rolled off,but the right driver and input tubes will bring them back.Can't beat em for this price.

Rated 5 out of 5 by from best KT88 on the market!After coming up empty handed in my search for the Penta KT88's (out of production), I contacted a few tube gurus and they pointed me to the ruby KT's. I've used 3 sets of Ruby EL34B-STR's and they're in my opinion, the best EL34's on the market. These KT's continue that trend.I tested these, JJ's, EHX and Svetlanas and the Ruby's had the cleanest, clearest sound with the tightest low end and richest and most open midrange. I highly recommend them. These are being used in my Splawn Nitro. After switching from EL34's to KT's the amp is much bigger, bolder and tighter.Parts express has the cheapest price on these by FAR. Expect to pay up to $40 more from other vendors. These arrived packaged well.

Rated 3 out of 5 by from Not my favoriteThis tube might work well for some people in a guitar amp. For an audio system, the RUBY KT-88 is a little too bright for my taste. Generally, I have not had good luck with tubes from China.

Rated 4 out of 5 by from Ruby KT-88 STRThese ruby tubes came with my CARY special edition V-12R monoblocks and the pair takes 24 KT-88 tubes. Prices for KT-88s range from $50-$200/pair. These ruby tubes are at the low cost end but perform beautifully and reliably with a 6 mos. mfg. warranty. I replace the whole set for only $600 and restored the amps to their original performance. An excellent value.
