Some things are very obvious such as non-original or reconed speakers, non-original transformers, replaced pots, re-tweed, re-tolex, re-grill, etc.and these changes are often disclosed and of a non-malicious nature.The earlier reissue models came with Standel built reproductions of the D130 - which use an identical cone weight and pulp formula and the same magnet energies (Danny Mc Kinney told me this). But he stopped making them because they were very expensive to make - so he began sourcing D130's. This amp has a 5 knob preamp - volume, treble, bass, contour and reverb. The reverb is really heavenly - it is very plate sounding - although it is actually a long tanked spring reverb.
So it effectively doubles your wattage and creates a huge spatial sound if you place the cabinets in different areas of the room. To be honest, I haven't played much with it, because the 15" speaker is already huge sounding. Speaking of the speaker (haha), the amp does NOT come with original JBL D130's.Bob was approached by Paul Bigsby to design an amplifier for his pedal steel guitars.After many failed attempts the 25L15 was eventually perfected with the first one going to Speedy West.Enter My Tube Amp Parts Store Here Mobile users Enter My Tube Amp Parts Store Here Home - Ordering Information - Ordering Information - Pay Pal info - Returning parts - Search the Hoffman Amps parts catalog What's New - Q and A - Links - Shipping Info/policy - E-mail Me - Amplifier Service Technicians - About Hoffman Amps Hoffman Amplifiers Customer Loyalty Discount Program Information Sound Clips - LED Bike light build info - Guitar Rig and Behringer FCB1010 info The Tube amp Library of information Click the link above for Tube amp info, Schematics, Board building information, Projects, Mods, Transformer diagrams, Photo's, Sound clips.There are hundreds of pages of Tube amp information on my library page.Please visit my Tube Amplifier Forum Here's the place you can go to ask tube amplifier questions.
