New cab day! After searching high and low for an old BF Tremolux cab, and failing in my quest, I pulled the trigger on a repro cab. Transport costs to Europe make it a bit pricey, and I am still kicking myself for not seeing that there was an "aged grill cloth" option. But I am very pleased with the result. It sounds noticeably better than the old "home brew" cab did - really great actually - and I feel that my beloved 64 T-lux is now all set to give its best.
