Kimber 4VS Speaker Cables
Our ultimate cable for transparency, low level detail, and top end clarity.   I've been using various Kimber options in my audio systems for years, actually since the late 80s.  Ray Kimber made nice stuff and his 8TC/4TC speaker cable was excellent. 

The 4VS utilizes four conductors of Ultra-Pure Copper for the + lead and four on the – lead, a total of eight conductors combining to make a 13 gauge cable. The VS Series use gray and black conductors in a polyethylene jacket.

Common to most all Kimber cables is the company’s proprietary VariStrand™ braiding technique and Ultra-Pure copper.

  • Conductors: (8) Ultra Pure copper
  • Stranding:   4 positive~4 Negative for 13 gauge
  • Braided Outer Jacket
  • (Cp) parallel capacitance: 340.0 pF @ 20 kH
  • (Ls) series inductance: 0.596 H @ 20 kHz
  • (Rdc) dc loop resistance: 0.041
  • (Xt) total reactance: 0.075 @ 20 kHz
  • Frequency response  0.5 dB dc - 250 kH
  • Neutrik® 1/4" Jacks (All MALE ENDS)
  •  Two 3ft Speaker Cables

AST Pro NL Panel
Larger Port ~ Switchable External Output
Now with Night Light Hookup!!


I love the stock AST but this REALLY lets the beast come out of the cave, so to speak, opening her up, allowing the amp to breathe with more airy and open sound. And this is before the positives of the additional switchable external output, allowing you to drive a cabinet (8 ohm preferable) with ease. This is literally a "cant miss" upgrade and as simple as plug and play.  NEW Now is made to accept the in and out of the Night Light Attenuator; plug in with no hassles!

  • AST Port enlarged over double the size
  • Opens the beast up! Less constricted Sonics
  • Easy access "switch on the fly" External Out
  • New Can Run Night Light Attenuator!
  • Panel perfectly matches the stock AST
  • Four Screws ~ Harness ~ Plug and play easy install

Get the panel with just the enlarged port or go for the full high hog PRO Panel with the large port, External out, switchable on the fly while playing, and Night Light hookup.

Reverb Tank
Replacement Swart Reverb Tank

Having reverb issues?  Have you switched the RCAs on the chassis, first? Sometimes they get switched by accident, dropping the reverb to nil.  Test first.   Is your 12DW7 in good shape?  A weakening 12DW7 can cause issues.  Lastly, you can open up the tank and examine the tiny wires at the end to make sure they are intact.  These can sometimes get separated with  rough handling during shipping or transport.  If you need a tank, this is our stock unit.  Just specify amp in comments area.  This is a drop-in replacement (RCA wires not included).  Of note, we now stock a slightly different reverb tank then the earlier silver unit.  This new piece is compatible with all Swart Amps, past or present.

Swart Rubber Feet
Replacement Feet for All Swart Amps

On many of the earlier Swart options, we used different types of feet.  For instance, many of the earlier ST-6V6se came with the METAL feet and the AST came with both metal and various rubber options.  Now you can replace any damaged feet, or simply upgrade to the current option used, this with the two types in play at right.  We now use the Small Rubber Feet (top right) as stock on the ST-6V6se, STR-Tweed, and AST.  The Large feet are currently on the AST Pro, heads, and speaker cabinets.

Swart Amp Replacement Tubes

Due to all our tube stock needing to head direct to new amp builds, we're passing the backup and replacement tube purchase to our friends up North, The Tube Store.   Please proceed to the order page from the screenshot at right or the link below.  We strongly encourage getting a backup set of tubes right off the bat, this to aid in testing and if a tube issue does arise.  Although we love NOS tubes, tubes listed are recommended due to current production and availability. See tube needs for each amp below.

Swart Tube Order Page  ~

NOTE: The current production **TUNG-SOL 6V6GT** has a propensity to red-plate when pushed hard.  If you do opt for the T-S 6V6, make sure the IP number is 30 or less.
