This laser that sat in storage for a few years but I forgot to take the batteries out and they leaked inside the laser unit. I tried cleaning the contacts but honestly I don’t have the time to mess with it. Hoping someone with more skill and time can get it working again because it’s a nice kit. Laser Unit: Bosch GRL 240 HV rotary laser Does NOT power on Battery leakage inside the housing I cleaned what I could but did not do a full internal repair For parts or repair only Model: 3 601 K61 C10 Serial: 312001143 Runs on 2x D 1.5V batteries Assembled in USA Everything Else is There and in Good Shape: -Bosch LR 24 laser receiver with rod clamp -Bosch BT 152 aluminum tripod -Bosch GR 8 C graduated measuring rod -Red laser enhancement glasses -Wall/ceiling mount bracket -Original hard carry case -Original manual The accessories alone are worth picking this up. Someone who knows what they’re doing could probably clean the board with isopropyl and get this thing running again. I just don’t have the bandwidth for it right now. What you see is what you get. Photos are of the actual item.

Our Ultimate Kit for Marantz Receivers includes everything you need to electronically restore and upgrade your Marantz. Our kits use only the highest quality parts from authorized distributors. These kits save you valuable time and headache in sourcing the parts yourself. Having serviced and restored virtually every Marantz receiver in the past, our kits are accurate and vetted. If you can solder and desolder, consider yourself handy in any other way, and are deliberate and thoughtful, you can do this! Any audio gear over 20 years old can benefit from this procedure. Any unit over 30 years old risks failure of other parts without it. Electrolytic Caps drift and fail with time leading to a less detail, transient response, weak bass and mushy overall sound as well as potential failure leading to costly repair. The sonic difference will likely astound you. Customers consistently tell us how much better their unit sounds after a restoration using our kit. A restored unit also greatly increases its value. We can provide more details on this unit if you’d like. Our documentation isn’t top secret. Parts are separated logically by board. All signal path caps 4.7uf or lower are replaced by sonically superior film caps, most by Wima. All transistors are made by OnSemi. Electrolytic caps are primarily Nichicon. Panasonic, United Chem-Con and other reputable brands are also employed. Nichicon caps used are primarily from the UPW and UKL line. Panasonic caps used are primarily from the FC & FR line. Relays are primarily Omron. Trimmer are made by Bourns. All Parts Are Procured Directly through the Manufacture or via Authorized Distributors. Ultimate Kits include the following. Replacement Caps for every electrolytic or tantalum cap in the unit, including tuner sections. Unless otherwise noted, this includes any off board capacitors including the Filter and Coupling Caps. Off Board caps may be smaller in diameter than the originals, our documentation provide a few easy options for installing these. Replacement Trimmers for critical audio adjustments like bias and dc offset (where applicable in amplifiers and receivers). Other Kit supplier do not include these. Replacement Relay where applicable. Not all units use a relay, not all vintage relays have a modern replacement, and finally not all vintage relays can be ascertained from available data. Kits are priced accordingly, you can view our parts list to see if your kit includes the relay(s). Replacement Transistors and diodes for those we now know were problematic. Not all transistors and diodes are replaced, nor should they be. Our Parts List shows all the transistors and diodes included. Many units made after around 1982 have few or none of these problematic transistors. Included Documentation (PDF format). Our Parts List (separated by board and part type – easy to comprehend). The Service Manual or at least the schematic if we can’t locate the full service manual. Our exclusive and extensive Hints & Instructions Document. The Owner’s Manual (if available). Parts are separated and bagged by board. Need a Kit for Something Not Yet Listed?

Up for sale here is this complete rebuild set for a Harman-Kardon 730 receiver. This is all the parts you need to rebuild a Harman-Kardon 730 amplifier board, tuner board, phono board, preamp/tone board, switch board, power supply board, and replace the four main caps. The phono board on the 730 is incorrectly designed, resulting in poor sound. This kit contains parts and instructions to fix this, which is fairly easy–you just have to change the values of four capacitors. Over time, capacitors and transistors start acting up and need to be replaced. The old parts are weak and failing. We will make them new again! This kit includes: Amplifier board kit: 8 capacitors (Nichicon PW, Panasonic FC). Tuner board kit: 19 capacitors (Panasonic FC, Nichicon PW, Wima film). Phono board kit: 12 capacitors (Nichicon PW, Wima film). Preamp board kit: 14 capacitors (Nichicon PW, Wima film). 2 zener diodes (Onsemi). Switch board kit: 2 capacitors (Nichicon PW) 4 transistors (Fairchild/Onsemi). Power supply board kit: 4 capacitors (Nichicon PW, Panasonic FC). Rectifier/Main capacitor board kit. 4 new main capacitors (Epcos 4700uf 50v). 1 piece of wire (to help in installing main caps). These are extremely high-quality genuine parts, and they are what I use when I rebuild vintage gear. I recently rebuilt a Harman-Kardon 730, which is what made me put together this kit. This should fix most problems with the 730. I will include surprisingly well-written instructions, but this is a moderately complicated rebuild, though it’s not too bad, and you should know what you’re doing and have a decent soldering iron and a dim-bulb tester with a 60W or 100W incandescent bulb. Please see my pictures for details. If you have any questions, please ask. Looking for more parts? I have power switches. White LED fuse lamps. Blue LED fuse lamps. 6.3v bi-pin bulbs. Wired 8v 60ma bulbs. New main capacitors for the Marantz 1060/2230. Wired Pioneer speaker plug replacements. New 630v yellow film capacitors at 13 different values. A large variety of transistors for vintage stereo repair.
