US made, integrated tube preamp able to handle KT150 tubes?

@lancelock - Thank you for the kind words! @jtcf -  I don't offer an integrated per se, but all of my amps have enough gain to be used without a preamp and also offer a volume control. Customized units are available as well if more gain, more inputs or a remote are needed. Feel free to contact me with any questions. Thanks for the mention! Best wishes,Aric

Most amplifiers that use the KT150 tube, are also backwards compatible with KT88 and EL34's so there are many tube rolling options available :-)
