Rumours of a “hot” IC‑705 service manual PDF appear on amateur radio forums and file‑sharing sites. In most cases, these are either (e.g. a manual for a different Icom model repackaged), incomplete drafts , or scanned copies of older service manuals that do not match the production IC‑705.
For example, the German QRP‑forum notes that the service manual details the two LN2306LT MOSFETs (Q31 and Q32) used in the USB‑C power circuit, along with a warning about using a freewheeling diode when driving inductive loads. Without the manual, such a repair would be guesswork. Similarly, the output amplifier transistor, an LDMOS, is rated for up to 31 W at 40 V, but the manual clarifies its actual safe operating area at 13.8 V. icom ic705 service manual pdf hot
