Hi all - I realize this is not the first "which transformers for a tweed Deluxe" thread. I've read what I've been able to find and have narrowed my options down to these pairs. I'd like to know what everyone thinks. They'll be mounted on a Mojotone 5e3 chassis. I believe that all of these PT's should help me hit vintage-appropriate voltages for a 5e3, unlike the Mojotone PT and others. I'm hoping for around 360-370V for a loaded 5e3, and I'd like to have a center tap so that I can use dropping zener diodes if necessary (I realize not all of these PT's have a high voltage center tap). Of course if I hit the voltage I'm looking for, I won't need to use the dropping zeners. (1) PT: Classictone 40-18016 - This is the Deluxe Reverb (et al.) transformer with lower, more appropriate, voltages for a 5e3. At Tube Depot: $62.96 With 2-1/4" x 2-13/16" Mounting Centers. The original 120V version! The classic! Great paper layer wound power transformer like originals! The basic 120V Deluxe type amp power transformer used from the '60s until the modern era. Suitable for use in the following amps: Deluxe, Deluxe AB763, Deluxe Reverb, Blackface Deluxe Reverb, Deluxe Reverb AA763, Silverface Deluxe Reverb, Deluxe Reverb AB763, Deluxe Reverb AB868, Deluxe Reverb A1172, Deluxe Reverb A1270, Deluxe Reverb with Volume Boost, Tweed Tremolux OT: Classictone 40-18022. At Tube Depot: $40.95 Paper layer wound output transformer that was actually replicated from a '50s original transformer! This is a must for the purist that wants the most accurate type replica for any 5E3 type project or for a "dead on" replacement!! Matches well with the 40-18021 power transformer. Suitable for use in the following amps: Original '50s 5E3 Tweed Deluxe (2) PT: Hammond 290BX. $68.57 at Angela Instruments.

Secondaries 330-0-330@120mA for high voltage, 50V bias tap, 5V@3A for rectifier, 6.3VCT@5A for filaments. OT: Hammond 1750E. $38 at Angela Instruments. 1750E Output Transformer For Tweed Deluxe! Replacement for '50s tweed Deluxe, Princeton, Princeton Reverb etc. Also handy for building amps using a pair of 6V6GT, 6BQ5/EL84 etc. in the 15 watt power range.

Mounting centers approx. 2&7/8". (3) PT: Allen (Heyboer) TP22D. From Allen Amplification: $99 Dual voltage secondary power transformer for both tweed and blackface Deluxes™. 270V-0-270V secondary for tweed and 320V-0-320V for blackface/silverface, both at 120mA continuous. 6.3V@3A heater winding and 5V@2A filament winding. Hum shield, copper flux band and heater center tap for lowest noise/hum emission. Old school paper-wound construction and made in the U.S.A! 2-1/4" by 2-13/16" mounting centers. 4.5 lbs. OT: Allen (Heyboer) TO22. From Allen Amplification: $69 High Quality output transformer is an excellent replacement for Deluxe™, Deluxe Reverb™ and 5E3 style amps using a pair of 6V6s in push-pull, a great upgrade for a Princeton™ or Princeton Reverb™ amp (bolts right on with no drilling) and is an awesome unit for 2xEL84 "18W" amps. Custom wound to stringent Allen specifications and made in the USA by Heyboer. 6,600 ohm primary to 4 or 8 ohm unit features the same core steel and ratings as the original vintage amps for great tone plus the option for 4 ohm "two speaker" configurations. Paper tube with paper-layered and specially interleaved windings. Durable and cool looking black oxide finish with 12" Unistrand pretinned leads for easy installation. Stainless-steel mounting hardware is included! The perfect choice for a 2x6V6 (or 2xEL84) amp where vintage tone and domestic manufacture are essential. 3-1/8" mounting centers, 2-1/4"H by 2-1/2"W. 1.6lbs. The cheapest are the Classictone, the most expensive are the Allen (Heyboer), and the Hammond are in the middle price-wise, but closer to the Classictone than the Allen ones. I'd say I'm leaning at this point toward the Hammond, but if I could be convinced that the Allen transformers were superior in every way, I could spring for those. I'm leaning away from the Classictone ones merely on account of their using so many exclamation marks in their descriptions.
