I love these amps, I think they are one of the best amps every designed, 4 amps in one, All valve, amazing ability sound like fender, marshall, vox etc. Analogue Valve bad boy.. Truly amazing
I am cleaning up my gear, so check out a huge range that I will be adding including mores amps, pedals and guitars.

Back to this amp, I have a Head on offer but also available is the matching speaker cab and a combo version.
This amp is technically brand new, never played. I purchased a , DT25C and DT25H and matching cabs at the same time, The DT25H was a backup for any issues and I haven't had any so its never been used. Images shown are placeholders from the net as the heads packed away. but it is as new.

About the amp
Four Boutique Tube Amps In One
The powerful combination of reconfigurable analog components and HD modeling allows DT25 to be four amps in one capable of producing American cleans, British crunch, class A chime and modern high-gain. Selectable operating class, power tube mode and four Voicings (which offer the perfect combinations of negative feedback loop topology, and HD preamp and tone stack modeling) can dial in classic vintage tones or be shaped into highly customized originals – and each one drips with boutique tone and touch-response.
Reconfigurable analog power amp: The power amp's analog components, including the negative feedback loop, can be reconfigured to match different amp models.

Four distinct voicings: Users can select from four different "voicings" that serve as a foundation for the amp's tone:
• Voicing 1: Classic American clean
• Voicing 2: British crunch
• Voicing 3: Class A chime
• Voicing 4: Modern high-gain

Power and operation mode switches: A switch on the back allows users to select between a lower volume mode (10 watts, Class A, cathode biased) and a 25-watt mode (Class AB, fixed biased).

Pentode/Triode switch: This switch changes the power tubes' configuration to offer additional tonal variations.

Integration with POD HD: When connected to a POD HD via L6 link, the DT25's analog components automatically reconfigure to perfectly match the digital amp models on the POD, allowing for an unprecedented level of versatility and realistic tone.
Two channels: The amplifier has two identical preamps, each capable of being set to any of the configurations, and users can switch between them.
