A finely tuned replica of the JTM-45 using a custom wound version of the Radio Spares output transformer which has 6.6K, 8K, 9K and ultra-linear taps on the primary. The 6.6k primary is used as on early JTM-45's. This relatively high primary impedance works well with 6L6GC/5881 tube types and of course KT-66's. EL-34's can be substituted after re-biasing. The Classic 45 with these tube types is rated at 35 watts. Additionally the Classic 45 can be fitted with 6V6's when using a 5Y3 or 5U4 rectifier. Re-biasing the amp for this tube type is also necessary.
The Classic 45 is a Bass circuit as were all early JTM era amplifiers. Early plexi tone control values are used consisting of a 56K slope resistor and 270pf capacitor. Filtering in the Classic 45 is low giving the amp a soft feel. Each stage is 32uf with tone control stage and preamp sharing 16uf. Plate voltage is 465-470vdc with GZ-34 rectifier. The Classic 45's power transformer is selectable for 120v, 200v, 220/230v and 240/250v operation. This power tranny features connections with solder tabs as the originals for period correct looks. The R/S output transformer is selectable for 4/8/16 ohm operation. Try the 16 ohm setting with 8 ohm cabs for a more dynamic response/feel from the amp.
Each amp I personally hand build using the finest parts and materials. Spot welded aluminum chassis, PEC 2 watt mil spec potentiometers, heavy duty Carling switches, Cinch tube sockets, Cliff jacks, BCR, ARS and F&T electrolytic capacitors, “Sozo” brand coupling capacitors and carbon film resistors mounted on a hand drilled turret board completes the interior layout of components. Original diameter copper stranded wire is used for all wiring. Each amp is laid out and assembled as an original JTM-45 would be.
The Classic 45 faithfully replicates the tone of an original JTM-45, only better! This amp is a delight to play being just at home doing "Beano" era Clapton as it is replicating AC/DC to early ZZ Top. The Classic 45 goes from an amazing clean tone to the best crunchy overdriven sounds imaginable. Excellent bottom end, incredible frequency response and exceptional 3D balance are all there to enjoy. The Classic 45 takes pedals extremely well and is not overly compressed sounding.
Classic 45 is shipping with either KT-66 or SED “winged C' 6L6GC and Tung Sol 12AX7's for 2008. Tube/ss rectifier switch is available upon request at no charge.
"The amp not only excels in tone and feel, but also has allowed me to sell half my other amps...I have never had an amp that was so expressive, brought the passion in your heart to your fingers, and was transferred to the audience in tone." - Harmony Central review
"If you're looking for an affordable boutique amp that can faithfully recreate the most vintage of all Marshall tones ... you'll have to look long and hard to find an amp that does it better than the Classic 45. Germino has done a great job of capturing that elusive and irresistible vintage Marshall magic. Well done! - Guitar Player Magazine (September 2004) - Read the full review (7.9MB PDF)
