Product Overview
Monitronics BSM35-3316E is a through-hole CRT flyback transformer built for horizontal deflection and high-voltage generation in CRT monitors. Common in Monitronics video chassis and assemblies used in 1990s and early 2000s commercial arcade cabinets - multi-game conversions, sports cabinets, driving rigs. The unit integrates an internal high-voltage rectifier diode array, dual focus adjustment pots (Focus 1 and Focus 2), and a thick silicone-insulated HV anode lead terminated with a gray elastomer suction cup anode connector. Low-voltage and deflection primary and secondary pins are embedded in an epoxy-potted through-hole base. Also tracked as BSM35-3313D. Cross-references to HR Diemen HR 47098.
Key Features

- Integrated internal high-voltage rectifier diode array
- Thick silicone-insulated high-voltage anode lead with gray elastomer suction cup anode connector
- Red, blue, and white silicone HV leads with gray strain relief
- Multi-pin through-hole base - epoxy-potted, low-voltage and deflection primary and secondary pins
- Factory label confirms dual part numbers: BSM35-3316E and BSM35-3313D
- Production sequence stamped: 040422-201; chassis trace mold mark: 241-3; stamped code: 141 4DN4E
- Cross-reference: HR Diemen HR 47098
- Application: Monitronics CRT monitor chassis, horizontal deflection and high-voltage supply
Applications
- Arcade monitor technician diagnosing a completely dark screen - no neck glow, no raster - desolders the failed flyback from the Monitronics chassis and drops this unit in as a direct board-level replacement
- Arcade preservationist restoring a 1990s multi-game cabinet or driving rig where arcing or ozone smell points to a failing HV section - swaps the BSM35-3316E to restore the high-voltage line without resorting to poorly cross-referenced substitutes
- Retro CRT monitor restorer tracking down horizontal deflection collapse in a vintage monitor - replaces the flyback to bring back a stable picture and correct focus on both guns
- Hobbyist or maker repurposing a salvaged arcade CRT monitor chassis for a custom build - retains original flyback pinout and dual focus control for a cleaner integration than a generic substitute allows
Frequently Asked Questions
Does this cross-reference to the HR Diemen HR 47098?
Yes. HR Diemen HR 47098 is a confirmed cross-reference for the Monitronics BSM35-3316E. Buyers sourcing an HR 47098 replacement should verify pinout and focus pot configuration against their chassis before installation.
What are the two part numbers on the label - BSM35-3316E and BSM35-3313D?
Both numbers appear on the factory label of this unit. They are Monitronics tracking numbers for this flyback transformer. Either number may be referenced in arcade monitor chassis documentation.
Is the anode suction cup and HV lead included?
Yes. The gray elastomer suction cup anode connector and the full silicone-insulated HV lead assembly are integral to the unit - not removable accessories. Red, blue, and white HV leads exit via a gray strain relief.
Has this been function tested?
Evaluation: Visual inspection only. Function testing not performed. The unit is unused NOS with all pins, leads, and connectors intact and no visible damage.
Is this compatible with non-Monitronics arcade monitor chassis?
Compatibility depends on your specific chassis pinout, voltage requirements, and focus pot configuration. This transformer was designed for Monitronics video chassis assemblies. The HR Diemen HR 47098 cross-reference may help match against other chassis documentation. Confirm pinout against your chassis before ordering.
Monitronics stopped making these. The arcade keeps running because someone saved a box of them - and this one never got installed. Yours now, if you need it.
