Swart STR Tweed
STR-Tweed Specifications
5W CLASS A ~ JUST INSANELY BIG TONE BREAKUP!
Single-Ended Output - Zero Negative Feedback
100% Tube Circuit - GZ34 or 5Y3 Valve Rectifier
Big Swart Tube Reverb - Foot Switchable
Hot and Clean mode Switch
Powered by choice of 6V6 or 6L6 (6V6 stock option)
JJ 12AX7(2) - JJ 12DW7 - EH 6V6GT - JJ GZ34 Rectifier
Point to Point Hand Wired Circuit
Cathode Biased (no need to bias)
Carbon Comp Resistors ~ Mallory Caps
Cloth Hook-Up Wire
Hi/Lo Input for High & Low powered Pickups
Heaters referenced to ground
Standby Switch for tube warm-up, extending tube life
All Swart Amplifiers employ Star Grounding
4/8 ohm 1/4" Out - Drive other Speaker/Cabinet
Switchcraft 1/4 inch inputs and output
CTS Potentiometers
Custom High Quality USA Built Swart Spec Iron
Speaker: 12" Mojotone BV-30H ~ 8 ohm
Finger-Jointed, solid Pine Cab w/ Lacquer Tweed Cover
Vintage Jewel Lamp ~ Circuit Fuse Protected
Pre-2015: 17" W x 9 3/4" D X 16 3/4" H (w/feet) ~ 29
2015: 17" W x 10 3/4" D X 16 3/4" H (w/feet) ~ 29.5
The point to point, hand-wired STR-Tweed has three driver/preamp tubes comprised of two 12AX7s and one 12DW7 with a parallel Reverb stage utilizing the 12DW7 & 12AX7, providing the circuit with virtually zero insertion loss. And like all Swart amplifiers, the STR-Tweed is tube rectified by the JJ 5AR4/GZ34 for the best AC filtering bringing great compression and tone, avoiding the typical solid state harshness that seems to ride along with solid state rectification. Try a vintage 5Y3 for a bit more SAG and less voltage on the power tubes.If you look at the specs above, you'll notice a lot of familiar attributes, such as cloth covered hook-up wire, carbon comp resistors, quality Mallory caps, and a circuit optimized with testing done by LISTENING....and MORE listening. Whether with the BV-30, this amp kills it..And like ALL Swart amps, STR-Tweed utilizes the Swart philosophy of minimal controls for the least complexity, something we feel is instrumental in great tone. Wonder why we go with a simple "treble" cut in the circuit? There's the answer. You wont see a plethora of controls in the Space Tone series because we've found it compromises our #1 goal: The best tone out there.
