Sansui Amplifier Repairs Sansui G This was not working, not surprisingly, found the left channel had blown loads of resistors and transistors. I replaced them and after powering it up, luckily, on a mains limiter as it was in overload. Turned out the preset for the quiescent was open so the outputs were being turned fully on. Replaced both presets ohm worked fine, replaced several capacitors on the driver and PSU boards while I had it in bits! Sansui G This one had blown the 2. The output transistors had also blown. I also replaced the driver transistors and one of the temp sense transistors by using a BC L. It also needed the panel lights replacing 8V mA. Sansui AU The speaker relay was switching on-off, I eventually found that four ohm fusible resistors were open circuit and 6.

In terms of power and clean headroom it is the smallest of all the Fender piggy back amps. The blackface Tremolux and Bandmaster AB are almost identical amps, just that the Tremolux is sized for smaller events and gigs. The Tremolux had tube rectifier, while the blackface Bandmaster had diode. Both amps had tremolo but no reverb. The sound is nice and clean and the tone remains relatively clean when one turns the volume knob.
The video clip demonstrates a blonde Tremolux, which is quite similar to the blackface.

Both woofers were sourced to be the correct AlNiCo magnet versions, with the ‘damping ring’ as the original pair had too many issues we repeatedly found with our AF Gen Sweep processes. The original surrounds on AR-3a woofers were typically ‘distorted’, so we sent these to our local, ‘been in business 40 years’ speaker shop for fresh surrounds. The ‘spiders’ were also slightly ‘deformed’ we didn’t notice this as it is a rare condition on most speakers, was hard to see, but would show up at 3 different frequencies on an AF generator sweep, but most noticeable centered at 80Hz , so he ‘painstakingly’ replaced them, while retaining the original VC’s and Cones retaining the original Voice Coils and Cones made the process logarithmically more difficult.
We have completely tested all drivers. All drivers were removed and tested individually. Attenuators removed and ‘burnished’ for ‘intermittent-free’ performance. Felt feet were installed to the bottom plates. Cosmetically, the grills were cleaned, and the original ‘hot glue attachment’ replaced with Velcro. We also added a ‘pull tab’ to facilitate removal. Grill frames intact with NO cracks or breaks. Our tech was able to make the ‘real wood’ Walnut veneer cabinets ‘presentable’ and they just had a fresh coat of ‘Restore-a-Finish’, then ‘Feed-n-Wax’, then buffed.

About Guitars Buying a new guitar is a considerable investment for most of us. An instrument is all about inspiration. You are the musician and the guitar is the tool you use to express your feelings and music. This has nothing to do with what models you choose or how much they cost.

Specifications[ edit ] The Hot Rod Deluxe is an all tube combo amp rated at 40 watts. It utilizes a single inch Celestion A-Type Speaker. The Hot Rod Deluxe is a mono-channel amplifier featuring 3 switchable gain levels: Footswitch and External Speaker jacks are also built in. Electronics and construction[ edit ] As an all-tube pre-amp and power sections combo guitar amplifier, the Hot Rod Deluxe features a pair of 6L6 GC beam tetrodes for the power section and two 12AX7 dual triodes for the preamp section.
One additional 12AX7 tube is utilized for the phase inverter of the power section. However, the rectifier , reverb driver and recovery, and effects loop circuits are solid state. The power section uses a “fixed bias ” biasing scheme with an adjustable bias potentiometer installed from the factory. The factory bias is 60 mA total for both 6L6s. The physical appearance of the Hot Rod series is based on the mid-to-late ’50’s “narrow panel” tweed amplifiers with accouterments such as a top mounted, chrome plated chassis and black “chicken head” pointer knobs, but with textured black tolex found on Fender amps from the s onward rather than the tweed covering.
Internally, there are two sets of circuit boards. The main circuit board contains the majority of the electronic elements and provides the base onto which the potentiometers for the various controls, and the input and output jacks, are mounted. A secondary board provides the base onto which the tube sockets are mounted although the pair of power tube sockets are mounted directly on the chassis with long leads connecting those to the secondary board.

The source-date code on a pot is a 6 or 7 digit code impressed into the casing of the potentiometer. For speakers this code can be 5, 6, 7 or 8 digits long, and it’s ink-stamped or paint-stamped on the “bell housing” of the speaker. In either case, the code works the same. The first 3 digits on a pot, or the first 2, 3 or 4 digits on a speaker are the source or manufacturer code. The remaining 3 or 4 digits are the date code. In 3 digit dates code, the 1st digit is the last digit of the year.
On 4 digits date codes, the 1st and 2nd digits are the last two digits of the year. In either case, the remaining 2 digits are the week of manufacture 01 to With this in mind, remember if the last two digits of the source-date code are greater than 52, you’re not looking at the source-date code!

Are you looking for an amp that can handle rehearsals with the band and practice at home, with the tonal flexibility you need for recording sessions, as well as enough power for gigs? The Peavey Classic series was first introduced in the early s and has by all accounts been a big success for Peavey.

You may compare these with your own speakers to determine what you have. Speakers are like ice cream; we all have our favorite taste. Some like strawberry while others like chocolate. What someone finds harsh can be beautiful sparkle to others. Speakers can have different frequency response depending on materials and construction design, like cone shape, magnet weight and coil size.
New speakers will therefore sound different from vintage speakers. There are of course exceptions to our preference of American speakers. One is a heavily cranked amp with a bright single coil guitar. The amp has a huge bottom end and a slightly edgy Fender 6L6 push-pull class AB cranked tone. Think of Keith Richards. Another example is a bright jazzmaster with bridge and neck pickup combined for some jangly surf tone, through a big clean amp like a Pro Reverb, Super Reverb or Twin Reverb with lots of reverb.
In some cases we want more power and headroom, particularly in small single speaker amps like the Princeton Reverb and the Deluxe Reverb who were poorly equipped from the Fender factory it is a big shame that the Jensen C12n never was installed in the blackface Deluxe Reverb.

Part 15 — Open Baffles and Bass When you think of a speaker, you think of a speaker in a box. Peter Comeau explores the alternatives With the exception of panel speakers like electrostatics, an enclosure and a drive unit seem inseparable. If we look at the early history of loudspeakers, however, it is littered with, what we now call, open baffle speakers.
Having been brought up in the hi-fi tradition of speakers in boxes I remember being horrified when I first discovered an old radio with a perforated back plate. Surely the front and back waves would cancel each other out?
Again, for a speaker in an enclosure, we would normally select a Q > for a closed box speaker and a Q.
