EHT number of AKAI TV 2205 - Akai Televison & Video

The EHT number for a Philips TV model 21PT3525/V7 can vary depending on the specific version of the TV. However, the EHT number for this model is typically BSC25-0235 or BSC25-0217.
It's important to note that replacing the EHT can be a dangerous process, as it involves working with high voltage components. If you're not experienced with electronics repair, it's recommended to seek assistance from a qualified technician who can perform the repair safely and properly.

eBay probably, or perhaps India Mart? In reality, the set is unreliable and needs replacing.

EHT or Extra High Tension is the power supplied to the final anode of the cathode ray tube.

The EHT is traditionally generated by the line transformer from the flyback pulse of the line oscillator/amplifier.
The generated high frequency high voltage current was from the outset rectified by a thermionic diode (eg. EY51, EY86) but by the late 1960s/early 1970s technology brought high voltage diodes and semiconductors rapidly replaced the old technology and the output from the line transformer then typically fed the anode via a semiconductor voltage doubler.

The rectified EHT was originally smoothed by a high voltage oil-filled capacitor but that was soon deleted in favour of spraying the outside of the CRT with a metallic paint and grounding it. This became the high voltage smoothing capacitor with the glass of the CRT being the dielectric and the final anode the positive pole...

If by eht you mean high voltage transformer, Google the model number with "parts" to see what is available or contact Philips.

Replace the EHT transformer.
