A Park 45LTD with NOS parts and Merren transformers is available at LA Vintage. This is the closest you’ll get to a vintage JTM45 currently made!

The Park 45 head and combo use modern and NOS parts to faithfully recreate the classic vintage British 45 circuit and sound quality. As in the originals, KT66 output tubes are used in the power section for a rich tone that sounds great clean and overdriven. At 30 watts clean and 45 watts fully cranked this circuit has been heard on countless seminal guitar recordings from the 1960s through the present. As with all Park amps we use carefully selected parts to recreate the sound and feel of the originals including custom USA made transformers (built the old fashioned way with paper bobbins), aluminum chassis, custom Park banana knobs, Park black plexi block logo and Celestion Heritage speakers in the combo. New feature: As or 2021 all Park 45 heads come with a push-pull control for Channel II’s volume control which adds brightness to this traditionally dark channel. This gives you increased tonal options.

New Version! All Park Traditional models (including 45, 50 and 75) are available with a Post Phase Inverter Master Volume (PPIMV) on the front panel. Pictured below

Options include Voltage selector, Post Phase Inverter Master Volume, NOS caps and resistors

This particular Park 45 has some strategically placed NOS parts including Phillips "Mustard" coupling capacitors, a Sprague flat mica treble cap, Piher PI resistors and Allen Bradley carbon comp plate, cathode and tone-stack resistors
